Description
ZLB Vertical propeller axial flow pump are of rugged, heavy-duty construction designed to operate in a multitude of applications requiring the movement of a high volume of water at a low discharge pressure. They are used extensively for pumping water from sources including lakes, cooling ponds, tanks, rivers and oceans.
An ZLB corrosion resistant axial flow pump is a common type of pump that essentially consists of a propeller in a pipe. The propeller can be driven directly by a sealed motor in the pipe or mounted to
the pipe from the outside or by a right-angle drive shaft that pierces the pipe.
Main Range of ZLB Vertical propeller axial flow pump :
Flow: 650m3/h - 36000m3/h
Head: 1m - 11m
Liquid Temperature.: 2oC - 80oC
Outlet Dia.: 350mm -1600mm
Pumps In Workshop :
The main advantage of an ZLB Vertical propeller axial flow pump is that it can easily be adjusted to run at peak efficiency at low-flow/high-pressure and high-flow/low-pressure by changing the pitch on the propeller (some models only).
These pumps have the smallest of the dimensions among many of the conventional pumps and are more suited for low heads and higher discharges.
Applications for ZLB Vertical propeller axial flow pump include raw water intake, dewatering, storm water removal, and flood control. These applications are found in a variety of markets including: urban and rural municipal water, government, industrial and irrigation and more.
