TURNKEY DESIGN

Rising efficiency requirements, increasing equipment maintenance demands, and the high cost of continuous 24/7 frac jobs present significant challenges in the industry. As a result, the need for a durable, versatile, and long-lasting pump has never been greater.

Jereh is proud to introduce the EXCALIBERTM Frac Pump, designed to tackle these industry challenges while delivering exceptional performance. This pump offers an extended lifespan, reduced maintenance, and enhanced compatibility.

Engineered for continuous duty, the EXCALIBERTM Frac Pump can handle a powerful 3,500 bhp input. Its unique modular cast design eliminates the risk of cracking, which is a common failure point in conventional welded pumps. This innovative approach significantly extends the pump's lifespan, reduces downtime, and lowers maintenance costs. Additionally, the re-engineered integral herringbone planetary gearbox ensures smooth power transmission and minimizes wear and tear, further decreasing the frequency of repairs. Notably, the maintenance cycle for the power end is twice as long as that of a conventional pump.

Finally, the 3500 HD platform design supports both diesel and electric drives, reducing the need for spare parts inventory and lowering the overall total cost of ownership.
