3st Energy Saving Reciprocating Pumps - Hong Kong

price: contact company for price

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,
