Description：

YOULONG PETRO provides TWS600 and TWS600S pumps fully interchangeable with OEM original equipment. These reciprocating triplex plunger pumps suit intermittent well service work, including acid stimulation, cementing, snubbing and gravel packing operations, with a maximum input rating of 600 brake horsepower.

The SPM TWS600S variant is built to reduce downtime tied to routine maintenance. It delivers improved rod load behaviour and greater pressure handling capacity compared to standard models.

Its heavy-duty build allows technicians to complete service work quickly and with minimal effort. Operating with a 3-inch plunger, the unit achieves working pressures up to 15,000 psi. Fitted with a 2.5-inch plunger, it maintains consistent reliable performance at pressures as high as 20,000 psi. The pump design stops process fluid from seeping into the power end and creating contamination issues, helping extend the operational life of all internal pump parts.

 

Stroke Length: 6 inches

Horse Power : 600BHP (447KW)

Maxim Rod Load: 100,000lbs

Gear Ratio: 4.61:1
