1、 Function Introduction
The DCB-B series low-noise high flow hydraulic gear pump adopts helical gears, which have low noise, high flow rate, small pulse, and smooth operation. Used in hydraulic systems below 2.5 MPa for artificial, plywood machinery, forestry machinery, plastic machinery, etc., and can also be used for high flow oil transportation in oil stations and oil fields. After anti-corrosion treatment, it can transport water at a high flow rate and be used as a water pump.
