The machine is of high power (90kW), having the highest pumping capacity compared with the same domestic series

Adopting the international name brand products in fuel-pump, control valve and electrical equipment of hydraulic system, the machine can adjust itself to the working environment, and control system reliability ensured.

The most advanced and reliable hydraulic system adopts two 4 degree inner-pricker seal structure to eliminate the leakage of oil absolutely. Independent operating subsystem and oil circuit are convenient for maintenance, and the highest use of import-fitting ensures the high reliability of products. Adopting the superior S pipe distribution valve with high seal property, the pipe can be rinsed by scavenging pump directly. The "S" pipe is of low resistance and anti-abrasive, prolonging the operating life.

Hard alloy plate and floating sleeve of high strength is adopted, whose operating life could reach to 30,000 cubic meters and 15,000 cubic maters respectively under the regular pumping.

Good maintenance property promotes customer's convenience.
