The pump is designed based on API 610, API 682 standard. single-stage, pump-absorption cantilevered pump.The pump body is supported by centerline. It is Inhalation axial and radial discharge. Axial force adopts before and after ring and balance holes for hydraulic balance. Mechanical seals can be single face or double face balanced set mounted. The mechanism sealing have cooling, washing and sealing liquid system. The pipeline system is designed based on API standard. The max work pressure 5.0Mpa. The imbibing and discharged flange can be designed according to GB.DIN and ANSI standard. It is mainly used in petroleum refining, petrochemical industry, chemical industry and other industries for pumping petroleum and its products including crude oil, refined oil products, hydrocarbons, water, acids, alkalis, salts and other medium.

API 610 / ISO 13709 compliant – designed for refinery and heavy-duty industrial services.

Overhung, centerline-mounted, radially split volute casing – handles high temperatures with stable alignment.

Back pull-out design – allows internal part removal without disturbing piping or driver.

Rigid shaft with heavy-duty bearings – ensures low deflection and high radial/thrust load capacity.

Closed, semi-open, or shrouded impeller options – adaptable to various fluid conditions.

Wide material availability – includes carbon steel, stainless steel, duplex, and NACE-compliant alloys.

API 682 mechanical seal arrangement – standard, with dual seal options available.

Performance range – capacities up to 3,400 m³/h, heads up to 395 m, temperatures up to 425°C.

High Reliability and Long Service Life: Designed for heavy-duty, continuous operation with a design life of up to 20 years, significantly reducing the risk of unplanned downtime in critical processes .

Excellent High-Temperature Capability: With centerline mounting and optional cooling (e.g., finned bearing housings, fan cooling), these pumps can reliably handle fluids at temperatures up to 425°C (800°F) and even up to 450°C .

High Efficiency: Advanced hydraulic designs, tangential discharge configurations, and wide hydraulic coverage allow for high efficiencies and precise matching to duty points .

Ease of Maintenance: The back pull-out design significantly reduces maintenance time and cost by allowing internal parts to be serviced without disturbing the piping system . Modular design also ensures good interchangeability of components .

Low Vibration and Smooth Operation: The robust shaft, rigid design, and optimized hydraulics result in very low vibration levels, contributing to longer bearing and seal life .

Wide Performance Range: Available with capacities up to 3,400 m³/h (15,000 gpm) , heads up to 395 meters (1,300 feet) , and pressures up to 10.0 MPa , making them versatile for many applications.

Proven in Demanding Applications: Extensively used in refineries (e.g., crude, vacuum, hydrotreating, coking), petrochemical plants, gas processing, and offshore oil production
