Double Suction, Horizontal, Split Case Centrifugal Pump (PS Series)

The PS Series is a double suction, horizontal, split case centrifugal pump available in 46 sizes from 5x3-8 (125x80-210) to 36x36-31 (900x900-780) for heads up to 656 feet (200 m) and flows up to 80,000 GPM (18,000 m³/hr.). The PS Series has a maximum operating pressure of 435 PSI (30 bar) and a maximum operating temperature of 221° F (105° C).

The Paragon PS Series pumps are used for air conditioning, cooling towers, irrigation, and drainage pumping stations, power stations, industrial water supply systems, and fire fighting applications.

Applications

Waterworks, Irrigation, Air-Conditioning Systems, Drainage pumping stations, Power

stations, Industrial water supply systems & Fire fighting applications in refineries.

Operating Data

Discharge Diameter 80 ~ 600mm

Max Capacity 2000l/s

Max Head 170m

Max Pressure 16 Bar Standard, 25 Bar on Request

Max Temperature 105ºC

Pump Casing

The casing is axially split, which permits removal of the complete rotor without disturbing

either piping or the motor.

Pumps generating high heads have double volutes to reduce radial forces, ensuring

minimal shaft deflection and low bearing loads.

Replaceable wear rings protect the casing at the impeller running clearances. High

head pumps are also fitted with replaceable impeller wear rings.

Flanges drilled to DIN PN10 with options for flanges drilled to ISO, BS, or ANSI standards.

Impeller

The closed impellers have double curved vanes. The double suction design gives

practically zero axial forces. Each impeller is statically and dynamically balanced

according to ISO 1940.

Bearings

Both sides are grease-lubricated deep groove ball bearings, sealed for life. Oil lubrication

are also available as optional.

Bearings

On both sides this pump has grease-lubricated deep groove ball bearings, sealed for life, optionally oil lubricated.

Shaft Seal

Uncooled soft-packed stuffing box or uncooled single-acting, unbalanced mechanical seal, according to DIN24960, independent of the direction of rotation. For operating pressure greater than or equal to 232 psi (16 bar): balanced mechanical seal.
