Excalibur TM Pump
TURNKEY DESIGN

Facing the challenge of higher efficiency requirements on operation, equipment maintenance and cost of current 24/7 continuous frac job, the demand for a durable, versatile, and long-lasting pump has never been greater.

 

Jereh is proud to introduce the ExcaliburTM Pump, designed to address these industry challenges and deliver exceptional performance through extended lifespan, less maintenance and strong compatibility. 

 

This specially designed pump allows 3,500 bhp input at continuous duty. Its unique modularly casted design eliminates the risk of crack failure, a common failure point in conventional welded pump. This innovative design significantly extends the pump's lifespan, reducing downtime and maintenance costs. The re-engineered integral herringbone planetary gearbox delivers smooth and even power transmission, minimizing wear and tear, and reducing the frequency of repairs. The maintenance cycle for power end is twice that of conventional pump.


Re-designed lubrication line boosts a 35% reduction in lubrication resistance, ensuring optimal lubrication of critical components, minimizing failure rate and NPT. Optional JPCM helps monitor the pump's running state in real time, prevent unexpected failure and reduce the risk of catastrophic malfunctions.


The platform-based design of the 3500HD accommodates both diesel and electric drive applications, reducing the need for spare parts inventory and lowering overall TCO.
