Description of Horizontal Split Case Pump:
NMZ series are horizontal, single stage, axially split case, double suction, between bearing, centrifugal pumps. It's suitable for pumping clean water or slightly contaminated water or liquids which is physically and chemically similar to water, where large quantity and certain head are required. The axially split casing design makes it's easy to remove the upper volute casing and rotary components without disturbing the motor and the pipework. And the double suction impeller ensures high efficiency.
Horizontal Centrifugal Pump Design Features:
Axially pump casing
- The casing is axially split, the inline suction and the discharge nozzles are in the lower half casing, this design makes it's easy to remove the upper casing and rotary components without disturbing the motor and the pipework.
Dual Volute Casing
- Pumps generating high heads have dual volutes to reduce radial forces, ensuring minimal shaft deflection and low bearing loads.
Between bearing design
- Less shaft deflection due to the between-bearing design.
Wear Rings
- Easily replaceable casing wear rings, protect the pump casing from the abrasion of the impeller. The overall cost of operation is minimized.
Sealing Flexibility
- Pump can be sealed by gland packing or wide range of mechanical seals
