Product Description

Product Description

Based on advanced German technologies and professional technology certification, Depamu three screw pumps show obvious superiority in terms of special working conditions like a high viscosity, a high pressure, a high temperature, etc. featuring a long service life, few faults and reliable operation, and have won praise from users at home and abroad with many patents held of the first-rank international level and features including strong self-priming capacity, high efficiency, small size, low noise, stable delivery and no pulsation.

Application Scope
Application for delivery of fuel oil, lubricating oil, hydraulic oil and other lubricating liquids similar to oil in various fields like petroleum, architecture, chemical fiber, metallurgy, Li-ion battery, machinery, electricity, machine tool, shipping, glass, food, environmental protection, water treatment, highway, etc. In industrial field, three screw pumps are used as lubricating pumps; they're used as hydraulic pumps in a hydraulic system, transfer and boost pumps in a fuel oil system, and transfer and oil filling pump in a transfer system.

Advantages
· Uniform and continuous flow, no pulsation, high volumetric efficiency, low noise, service life remarkably longer than that of a gear pump or rotor pump.
· Strong self-priming capacity, no need in bottom valve or auxiliary evacuating equipment, reliable operation.
· Compact structure, small size, light weight, high speed allowed, not too sensitive to gases or pollutants, direct driving allowed by a motor or other prime mover.
· Pumped fluid without foam or turbulence, highly viscous and high-temp fluid transport allowed.
· Durable structure, easy mounting and maintenance.

Performance Parameters
· Capacity:max. 456m³/h  max. 7600L/m
· Differential Pressure: 20 bar, max. 40 bar
· Speed: max. 2900r/min
· Fluid Viscosity:3~760cSt
· Max. Temperature: 300ºC
