CBZ Type Marine Horizontal Self-priming Centrifugal Pump
CBZ Type Marine Horizontal Self-priming Centrifugal Pump Application
CBZ Type Pump is a kind of horizontal self-priming centrifugal pump. Its performance date is nearly same to the CWZ self-priming pump. The biggest difference is that this pump is in mono-block type. That is to say, the CBZ pump is connected to the pump directly, without intercoupling. (The CWZ pump is a coupling type pump)
With such design, the CBZ self-priming pump installation space is much smaller than CWZ pump. And also its cost is also smaller than the CWZ pump. So the price is much more competitive. It is very suitable for the small vessels, such as tugboat, barges, landing craft and so on. For the purpose of the marine fire pump, marine bilge pump, and other purposes.
Material for CBZ self-priming pump casing and impeller can be in bronze, stainless steel, and cast iron. The shaft is of stainless steel, shaft seal in mechanical seal type.
CBZ Series Horizontal Self-priming Centrifugal Pump is used at cabin bottom to cool water and firefighting. It is able to carry seawater under 80 degrees. Freshwater and other non eroding liquid. The pump rotates anticlockwise viewed from the motor.
