Plunger pump YOUKS SPM QWS2500SD/4"
This plunger pump is designed for use in oilfield acidizing and hydraulic fracturing installations. It maintains the high load capacity of the connecting rods, necessary for operation even in severe conditions, including hydraulic fracturing of shale formations. The equipment is designed for harsh field conditions and operates reliably continuously at ambient temperatures from -20℃to +50 degrees and relative humidity no more than 90% at +20 degrees.
Designed for the operating mode of an oil field hydraulic fracturing pump: continuous operation 6 days a week, 10 hours a day, total annual operating time of 3000 hours, as well as the possibility of continuous operation at maximum power for 3 hours.

The plunger pump provides a maximum operating pressure of 20,000 Psi when using a 3.5" diameter plunger and a maximum flow of 7,740 L/min when installing a 6.75" diameter plunger. While maintaining the specified performance characteristics of the power unit, the Buyer has the right to use plungers of different sizes depending on specific operating conditions.
The plunger pump supplied by the Seller must be equipped with a complete set of systems and components required for normal operation.
The seller provides a list of standard wear parts required for trouble-free operation of the plunger pump.
