An open impeller chemical pump, also known as a semi-open impeller pump, is a type of centrifugal pump that is designed to transfer liquids or fluids that contain chemicals, abrasives, solids, or suspended particles. This pump consists of a motor or engine, a pump body, and an impeller. The impeller is the main rotating component that generates the pressure and flow of the fluid by spinning inside the pump casing.
Application:
Chemical pump with open impeller is mainly used to transport clean or polluted, low temperature or high temperature, chemically neutral or corrosive liquids. The open impeller design also makes the pump easier to maintain and service, as there are fewer parts that can get clogged or damaged. However, this type of pump may be less efficient than a closed impeller pump in certain applications, as the fluid may recirculate within the pump and cause more turbulence and friction.
Operation parameter:
Caliber:25-400mm
Flow(Q):can up to 2600m³/h
Head(H):can up to 250m
Pressure(P): can up to 2.5MPa
Working temperature(T):-20℃~+180℃
Feature:
One of the key features of an open impeller chemical pump is that it does not have a shroud or cover around the vanes of the impeller, which allows the fluid to flow freely between the impeller vanes and the casing. This design makes the pump more tolerant of abrasive and corrosive fluids that can wear or damage the shroud of a closed impeller pump.
