Progressing Cavity Pump with Bearing Block

The MJ S-type standard pump features a traditional bearing block , enabling the installation of various drive systems. Its universal drive configuration enhances operational flexibility. The insert connection between the rotating unit and the drive shaft is easy to maintain, simplifying the replacement of rotating wear parts and the shaft seal.

Flow rate：Q ≤ 500 m3/h (2200 USGPM)

Pressure：P ≤ 96 bar (1400 psi / 9.6 MPa)

Flexible Drive Integration

Compatible with elastic couplings, V-belts, or other drive types thanks to a free bare shaft and traditional bearing housing design.

High-Pressure Stability

Equipped with bearing housing support to handle extreme axial loads, ideal for demanding applications like high-pressure sludge feeding in plate-and-frame presses.

Easy Maintenance

Quick-release plug connection between unit and drive system enables maintenance without bearing disassembly.

Low-Pulsation Conveyance

Continuous smooth flow unaffected by pressure/viscosity fluctuations—ideal for shear-sensitive media.

Precision Flow Control

Flow rate proportional to rotational speed, with high metering accuracy across a wide RPM range.

High Self-Priming Capacity

Efficiently handles viscous fluids and solids-laden media without cavitation.

Valve-Free High Pressure

Maintains consistent performance in high-pressure conditions without reliance on valves.

Durable & Quiet Operation

Robust construction ensures long lifecycle and low-noise performance even under heavy loads.

Seal Efficiency

Front-positioned mechanical seal eliminates flushing requirements in most applications.

Quick Stator Replacement

Simplified design allows easy rotor/stator swaps to minimize downtime.
