The pump guides articles provide guidance and reviews on different types of the pumps including prices. A pump is a device used to transfer or the fluid across different places. The pumps utilize the mechanical energy to transfer the fluid. The pumps convert the mechanical energy into the hydraulic energy of the fluid.
The mechanical energy supplied to the pump can be the manual operation, electricity, DC battery power, solar power, wind power, etc. The pump is one of the oldest forms of device used by the human. They can be dated back to the Egyptian civilization.
Nowadays, the pumps are used in a wide variety of applications such as drawing water from the deep wells, aquarium filtering, fountain formation, watering crops, pond aeration, washing and cleaning systems, water circulation system, fuel injection, cooling tower systems, boiler feed supply system, and fuel injection systems.
The pumps have also replaced our human organs in the medical industries. The artificial human heart is made to pump the blood through our veins with the help of the pumps. The pumps have become one of the vital devices of the modern-day world.
Pump Guides – Classification
The pumps are used for a such a long time by our humans and classified into a wide range depending on their operation, flow, power source, etc. It is almost impossible to cover all the types of pumps and their classifications. In this article let us have a look at the classification of based on their fluid operation. The pumps are classified into two types based on the way they move the fluid as
- Positive displacement pumps and
- Dynamic pumps.
Pump Guides – Positive displacement pumps
Positive displacement pumps operate by moving a fixed amount of the fluid from the suction head to the discharge end of the pump. They provide constant flow rate and volume of the fluid at the discharge.
They are used in applications with high-pressure and low flow combinations. They have high-efficiency rate. The output is provided in every stroke of the piston in the pump. They are further classified as the reciprocating pumps and rotary pumps.
Reciprocating pumps
Reciprocating pumps move the fluid by using a piston, plunger or diaphragm membranes. The valves are used to restrict the motion of the fluid in one direction. They can single acting or double acting based on the direction of the flow. They are further classified as
- Piston pumps
- Plunger pumps and
- Diaphragm pumps
Rotary pumps
Rotary pumps operate by a rotating mechanism that creates a vacuum. The vacuum pressure is used to suck the fluid in the pump casing. And the fluid is transferred using the rotary action in the pump. They can be further classified as
- Gear pumps
- Screw pumps and
- Vane pumps
Dynamic pumps
Dynamic pumps use the fluid velocity and the momentum created by the pump to transfer the fluid. In these pumps, the kinetic energy is imparted to the fluid to increase the flow velocity. They are used in high speed and high flow applications. They are less efficient than positive displacement pumps. They provide smooth and continuous operation. The dynamic pumps are further classified as
- Centrifugal pumps and
- Special pumps
Centrifugal pumps
They are the most common type of pump used in the piping system. A rotating impeller is used to provide the pressure and flow of the fluid. The fluid enters the impeller blade at an axis and is accelerated to flow through the discharge end. They can be classified depending on their flow direction as
- Radial flow
- Axial flow and
- Mixed flow – a combination of both axial and radial flow direction.
Special pumps
These pumps induce velocity in the fluid by special means such as electromagnetic induction, gas pressure, an ejector mechanism, gas lift, etc. They do not use rotating impeller action to impart velocity in the fluid. Some of the pumps that come under this category are:
- Jet pumps or Ejector pumps
- Electromagnetic pump and
- Gas transfer/Lift pumps
The pumps are furthermore classified depending on their operation inside the water medium or outside as submersible pump and pedestal pump. They can be classified based on their priming capability as self-priming pumps or manual priming pumps.
They are classified depending on their power source such as the electric pumps, DC powered pumps, solar pumps, diesel pumps, etc.
The classification of the pumps keeps going on and on. It is tough to accommodate all the types of pumps in a single article or even a book. In this article, we have a pump guide to select the pump depending on their operation, selection parameters, application, price range, and manufacturers.

Step-by-Step Quality Control & Inspection Procedure
The execution of quality surveillance for Pump Guides And Reviews is structured across four progressive QA/QC intervention phases:
Stage 1: Pre-Inspection & Engineering Document Review (Review Point – R)
Prior to commencement of any physical activities or manufacturing operations related to Pump Guides And Reviews, the contractor or vendor must submit all technical submittals to the Owner or TPI agency for formal review and approval.
- Verification of approved Inspection and Test Plan (ITP) identifying all Hold (H), Witness (W), Review (R), and Surveillance (S) intervention points.
- Cross-examination of Material Test Reports (MTR / Mill Certificates) against standard design specifications (ISO 9001 / ASME / API).
- Review and approval of specific Procedure Qualification Records (PQR), Welding Procedure Specifications (WPS), or calibration certificates.
- Verification that all measurement instruments, gauges, and NDT equipment hold valid calibration certificates from ISO/IEC 17025 accredited calibration laboratories (within 6 to 12 months validity).
Stage 2: In-Process Witnessing & Fabrication Control (Witness / Hold Point – W/H)
During the active execution phase, the certified inspector performs physical surveillance to ensure strict adherence to certified drawings, manufacturing procedures, and code tolerances.
- Verification of material traceability (heat number, heat treatment lot, plate number) transferred accurately onto fabricated components.
- Dimensional verification and visual inspection using calibrated gauges, micrometer depth dials, or laser alignment systems.
- Monitoring ambient environmental parameters (relative humidity, dew point, substrate temperature) when applying surface treatments, welding preheat, or pressure testing.
- Witnessing non-destructive examination (RT, UT, MT, PT, PMI) at specified percentages according to project critical rating and code requirements.
Stage 3: Final Acceptance, Pressure/Performance Testing & Marking (Hold Point – H)
The culminating milestone where the fully assembled or completed item is subjected to definitive acceptance tests in the presence of the Owner’s Third-Party Inspector (TPI).
- Execution of pressure proof tests (Hydrostatic at 1.3x to 1.5x MAWP or Pneumatic test) with dual calibrated pressure gauges and temperature recorders.

Common Non-Conformances & Field Mitigation Strategies
Based on extensive third-party inspection field records in oil & gas projects, the following deviations require heightened surveillance:
Defect / Hazard: Material Grade Substitution & Lack of Heat Traceability
Root Cause: Uncontrolled workshop storage, missing color coding, or unverified supplier sub-tier procurement without EN 10204 3.1 documentation.
Preventative Action: Enforce strict 100% Positive Material Identification (PMI) prior to cutting, and mandatory material receiving inspection with physical stamping cross-referenced to original mill test certificates.
Defect / Hazard: Out-of-Tolerance Fit-Up & Alignment Mismatch
Root Cause: Poor thermal cutting, thermal distortion from excessive preheat, or inadequate jigging and tacking arrangements.
Preventative Action: Establish a mandatory Witness/Hold point at joint fit-up before root pass deposition. Use calibrated Hi-Lo gauges to verify bevel angle, root face, and root gap according to the qualified WPS.
Defect / Hazard: Premature Coating Delamination & Blistering Under Film
Root Cause: Excessive soluble salt contamination (>20 mg/m²) left on the substrate, blast cleaning below dew point (<3°C above dew point), or oil/moisture in the blasting compressor air line.
Preventative Action: Perform Blotter Test (ASTM D4285) daily on compressed air, enforce Bresle patch chloride testing, and apply primer within 4 hours of abrasive blasting before rust blooming initiates.
Defect / Hazard: Pressure Drop During Final Hydrostatic Proof Testing
Root Cause: Micro-leakage through temporary test flange gaskets, entrapped air pockets inside vessel high points, or inadequate temperature stabilization.
Preventative Action: Ensure thorough venting at all high-point vents until bubble-free fluid emerges, allow minimum 15-minute temperature stabilization between filling medium and ambient metal, and torque all blind flanges with calibrated torque wrenches.
Frequently Asked Questions (FAQ)
Q: What are the mandatory qualifications for inspectors verifying Pump Guides And Reviews?
A: Inspectors must hold recognized international certifications applicable to the discipline. For welding and fabrication: CSWIP 3.1/3.2, AWS CWI, or API 510/570 Source Inspector. For NDT: ISO 9712 or ASNT SNT-TC-1A Level II minimum. For coatings: NACE / AMPP Level 2 or FROSIO Level III. Additionally, the inspection agency must operate under an ISO/IEC 17020 accredited quality management system.
Q: How does PtroTek resolve non-conformances (NCRs) encountered during vendor surveillance?
A: When a deviation from certified drawings or ISO 9001 / ASME / API is detected, the inspector issues a formal Non-Conformance Report (NCR) within 24 hours. The vendor must submit a Root Cause Analysis (RCA) and proposed disposition (Rework, Repair, or Concession). Work on the affected component is halted (Hold Point) until the Owner’s engineering authority approves the disposition and a re-inspection confirms full compliance.
Q: What is the difference between Witness (W) and Hold (H) points in an Inspection & Test Plan (ITP)?
A: A Hold Point (H) is a mandatory milestone where fabrication or testing CANNOT proceed without the physical presence of the designated client or third-party inspector. Written clearance or stamping is strictly required. A Witness Point (W) requires prior notification (typically 24 to 48 hours) to the inspector; however, if the inspector fails to attend at the scheduled time, fabrication or testing may proceed with subsequent review of the test records.
Q: Can international clients review inspection reports and photos in real time?
A: Yes. PtroTek provides comprehensive Flash Reports issued within 24 hours of inspection completion, followed by detailed formal inspection reports accompanied by high-resolution calibrated photographic evidence, dimension logs, and signed vendor test records for complete global transparency.
