Diesel Engine Hydraulic Pump

Product Description

Diesel Engine Hydraulic Pump
Product introduction
  • Diesel Engine Hydraulic Pump is special designed for dirty water and waste water transfer and treatment.
  • Pump is with self-priming structure, at the bottom of inlet, there’s a hole for unloading of solids left in pump.
  • It also could be equipped with diesel engine for wild application.
  • The unique structure of open impeller makes sure the free pass of solids in sewage with max size of 60% of outlet DN and fiber 150% of impeller diameter.
  • The sewage pump is widely applicable for the lines of urban discharge projects, light industry, papermaking, textile, foodstuff, chemicals, electric power, petroleum, mines, aquiculture and so on.

Frequently Asked Questions
What is the primary application of the Diesel Engine Hydraulic Pump?
This pump is specifically engineered for handling dirty water, sewage containing solids, and waste water treatment processes across various industries such as mining, aquiculture, and chemical plants.
How does the self-priming mechanism handle solids left in the pump?
The pump features a specialized self-priming structure equipped with a designated clean-out/unloading hole at the bottom of the inlet. This allows operators to easily clear out residual solids without dismantling the unit.
What sizing limitations apply to solid materials passing through the pump?
Thanks to its unique open impeller design, the pump facilitates the free passage of solids up to 60% of the outlet nominal diameter (DN) and fibrous material up to 150% of the impeller diameter.
What are the operational temperature limits for pumped fluids?
The pump is designed to withstand a maximum permissible fluid temperature of up to 80°C (176°F), rendering it safe for most warm industrial discharges.
What options are available for powering the pump?
The system is highly versatile and can be configured with either a 3-phase electric motor (220V/380V/400V/415V at 50Hz or 60Hz) or a diesel engine driver tailored for outdoor, remote, or wild applications.
