Description

Introduction

500WN is a reciprocating, horizontal single-acting, triplex plunger pump. Following the design of 500W, the main parts such as the connecting rod, crosshead, and fluid end are identical. However, the internal drive mechanism has been modified with less internal parts to enable easier maintenance with better performance.


500WN is rated at 500 brake horsepower maximum with 8”stroke. The fluid ends are available with sizes of 3 3/8”, 4”, 4 1/4”, 5” and 6”. The pump overall weight is about 6,129lbs, but may vary slightly depending on accessories. The fluid ends are available to accommodate different plunger sizes for the power end. Installed on fixed or mobile equipment, 500WN can be applied in all activities of oilfield operations, pumping water, cementing, fracturing or other mixed medium. 

Feature

Equipped with a lube pump which realizes self-lubrication of the power end.
Driven by worm pair, the input shaft movement direction is in parallel with the plunger.
Optional left and right pump which enables twin pump layout on one equipment.
Improved power end is easier for maintenance.
