NMZV Type Vertical Split Casing Centrifugal Pump

Vertical Split Case Pumps Description:

NMZV series are vertical, single stage, axially split volute casing, double suction, centrifugal pumps. It’s the vertically mounted type of NMZ series. They share the same volute casings, impellers and shafts. Comparing with the horizontal pump, vertical water pump only requires haft the floor space. So it can meet the needs where assembling space is limited.

Vertical Split Casing Centrifugal  Pump Design Features:

1.Vertically mounted design for space saving
2.Double suction impeller minimizes axial load, which extends the life of the wear rings, shaft seals and bearings
3.Independent bearing housing design allows to maintenance the bearing without removing the upper volute casing
4.Axially split casing design makes it’s easy to remove the upper casing and rotary components without disturbing the motor and the pipework.
5.Double volute design of some models can reduce radial forces and minimizes noise and vibration
6.Wear rings can protect casing form the abrasion of impeller.
7.High efficiency
