DJ /DJZ pumps are series of self-priming sewage pumps which are similar as Varisco & Victor’s pumps, with solids handling and resistance to abrasion. The self-priming sewage pumps can handle liquids to a viscosity of about 50 mm²/s. They are designed with the advanced maintenance hole and wear plate, easy to clean and flush.
DJZ series is a mono-block type of DJ pump. Motor shaft is plugged into pump shaft to ensure concentricity and shorten the axial length. It’s very useful when one or more of the following are required: self-priming, solids handling, resistance to abrasion or corrosion, limited installation space.
The self-priming pumps can be applied in many fields, such as industry, civil engineering, marine, waste treatment and so on. They also can deal with different neutral, alkali liquids, liquids mixed with sand, mud or other caustic soda and waste water resulted from washing, cooling, circulation, purification or emergency. Pump performance can be adjusted into different levels by speed (rpm) to meet different requirements.
Centrifugal sewage pump available with diesel engine and trailer mounted design upon request
