ZLB Large Capacity Flood Drainage Water Vertical Axial Flow Propeller Pump

   The large flow vertical axial flow propeller pump, surface installed, named ZLB in China. Also, we have submerged type if you are in  demand. 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.

Material of flow passage components:
The ZLB vertical propeller axial flow pump could be customized with different material,main material configuration followed :

1. Case&Cover: HT250; Stainless steel; QT500

2. Impeller: HT250; Stainless steel; QT500

3. Wearing ring: HT250; Stainless steel; QT500

4. Shaft&Sleeve: C.S 45, 40Cr, SS420

5. Column pipe: C.S.Q235

Construction Structure:

1. Installing mode:

Single foundation: pump and motor are installed in the same foundation with outlet above or under foundation.

Double foundation: pump and motor is separately installed in itself foundation with outlet between the two foundations.

2. Pump shaft is made of high grade carbon steel and is supplorted by two rubber of  plastic bearings with water as a lubricant.

3. In contact with rubber or plastic bearing is the shaft sleeve which is coated with a film of chromium in order to upgrade the anti-corrosive and anti-wearing effect.

4. The capacity and head of the pump can be changed by changing speed or adjusting vane angle according to performance table, if necessary.
