3ST series Energy Saving and High Performance Reciprocating High Pressure Pumps

MIE. has successfully developed 3ST series energy saving and high performance reciprocating high pressure pumps through three year’s cooperation with Zhejiang University of Technology. By adopting the technology of isochronous isolation system, the pump is a breakthrough in the seal construction of all kinds of existing reciprocating pumps. A sealing medium chamber is added to the seal structure of a reciprocating pump to make the sealing medium and transport medium reach the self balancing isolated condition.

With application of the technology of isochronous isolation, there’s no need for the use of auxiliary equipment to boost pressure required for cleansing the seal. The loss of power due to friction between the plunger and stuffing during the reciprocating travel is thus avoided by this new technology. The effect of lubrication of the sealing medium is thus fully realized resulting in prolonged life of the pump and durability of wearable parts.

This series of pumps have also employed the patented self-alignment technology of plungers used in reciprocating pump, which ensures the concentricity of the plunger, filler and guide sleeve during assembly, eliminates excessive wear of plunger, and minimize the loss of energy due to friction between plunger and stuffing and therefore enhances the reliability and durability.

As proved by Hefei General Electromechanical Products Testing Institute and National Pump Valves Quality Supervision and Testing Center through random sampling examination, the pump efficiency of 3ST series reciprocating pumps with the application of synchronous isolation technology has reached 92.2%, which is 7% higher than that specified in the National standard of GB/T9234-2008.

This series of pumps have employed the following five patented technologies:

1. Double flow-way combination valve for reciprocating valve, 
2. Plunger pump with synchronous isolation,
3. Hollow plunger assembly for plunger assembly pump,
4. Plunger pump assembly with double clamp rings,
5. Automatic alignment device for plunger for reciprocating pump.
