Material of Construction

WPIL LR split-case pumps offer many benefits. They

provide a wider range of hydraulic coverage than other

typical horizontal split-case pumps and end-suction

designs. Split-case designs allow for balanced axial

loading, high efficiency and low NPSH with double

suction closed impellers. Rugged, heavy-duty

construction coupled with superior design features

makes this line of pumps very reliable. Low initial

investment and high efficiency make overall cost very

attractive.

Also WPIL LR type horizontal split-case pumps are

designed to ensure ease of maintenance and parts

Interchangeability.

The pump shall be a horizontal, single stage, double

suction, and double volute axially split-case centrifugal

pump. The suction and discharge nozzles shall be

integrally cast in the lower half of the casing and on the

same horizontal centerline. The pump shall have a side

suction and discharge

The LN’s versatile centrifugal double-volute design

miniminzes radial thrust problems and allows the pump

to be operated at any capacity from design point back

to shutoff- without harmful effects from excessive

deflection. It is essentially a low deflection machine

shaft and casing is all engineered to minimize

deflection and consequent vibration. rubbing and

wear.
