API 674 High-Pressure Reciprocating Pumps

Our commitment to quality extends to our line of Reciprocating API 674 pumps, designed to meet the demanding needs of the industries. The API 674 standard is recognized globally for setting stringent criteria for reciprocating pumps used in continuous-duty applications such as petroleum, petrochemical, and natural gas processing. These pumps are meticulously engineered and manufactured to comply with these rigorous standards.

The pumps are designed to be resilient and to have reliable performance even in the most unfavourable conditions. This is ensured by using 3D Modelling, Reliability, Fatigue and Pulsation Analysis.

Benefits of Goma’s API 674 Pump Packages:

High-grade cast iron or SG iron (for low-temperature applications) crankcase with a top-open design to ensure easy maintenance and assembly.
Fluid Chamber available in a wide range of materials ranging from carbon steel, SS 304, SS 316/316L, Duplex SS to super duplex SS.
Different types of valve assemblies are available, suited as per applications such as Plate/Ball/Wing types.
Stainless Steel or Carbon Steel plungers with various types of coatings such as Hard-Chrome, Tungsten Carbide, or Colomonoy coatings.
As per applications Rope type, PTFE Aramid type, and V-Ring type plunger packing options are available.

As per customer requirements, Goma’s API 674 pump skids come with electric motors (FLP/NFLP), diesel/gas engines, foot-mounted gearboxes (as per AGMA 6013 or API 677), suction/discharge dampeners (bladder type or maintenance-free), safety instruments such pressure safety valves (as per API 526), vibration, pressure and temperature transmitters, etc.

We, at Goma, ensure that every pump package dispatched from our factory goes through a series of rigorous tests as mentioned below:

Mechanical Run Test of Pump Power End
Liquid End Hydrostatic Pressure Tests
Performance Tests at Full Load
NPSH Tests
Stress and Fatigue Tests
Vibration Tests
Noise Test
Strip Test

We have a wide range of API 674 pumps power frame sizes, each with multiple plunger sizes to accommodate different pressure and flow rates.

Notes:

1) Each Pump series has a different plunger/piston size to accommodate desired parameters. Discharge volume indications are based on 100% volumetric efficiency with water.
2) Maximum flow rate is at maximum plunger diameter. Maximum pressure is at minimum plunger diameter.
3) The flow rate varies with changes in viscosity and temperature.
4) For API 674 Process Pumps only
T/TG-8000 is now T/TG-8K
T-20000 is now T-20K
T-40000 is now T- 40K
T-60000 is now T-60K
T-80000 is now T-80K
For Water Jetting & Hydro Testing Pumps, these models continue to remain the same as before.
5) The API 674 process pump models are available in non-API 674 specification as well. The final specification will be decided as per application.
6) The flow rate varies with changes in viscosity and temperature

With our key innovation, continual improvement, R&D, and customer-concentrated approach, we have positioned ourselves at the zenith of cutting-edge pump design, solutions, and prompt customer service.
