Fire Pumps - Horizontal Split Case
pump

Description

Bristol Split Case Pump is a single stage, non-self-priming, centrifugal volute pump with radial suction and discharge port. This pump has a horizontal pump shaft with the impeller placed in the middle of the shaft and with self contained combination bearing housing and seal chamber on both sides of the impeller. Without disturbing the motor or pipe-work, the split case construction enables the pump casing to be dismantled in the horizontal plane along the drive shaft. Removal and dismantling of the internal pump parts e.g. bearings, wear rings, impeller and shaft seal can then take place.

Features

Characteristics

Description

Casing - (Ductile Iron) - Upper and Lower half bolted and dowelled to provide perfect alignment. Upper half casing can be removed for inspection, without disturbing bearings or alignment.

Shaft Sleeve - (Stainless Steel) - Protect the shaft against corrosion and wear, extends through gland for maximum shaft protection.

Impeller - (Bronze) - Enclosed, double suction, Cast in one-piece and balance to minimize the thrust and to ensure longer bearing life. Locked in position by shaft sleeve.

Sealing Housing - (Ductile Iron) - Designed to accept packing with lantern ring. Internally drilled liquid passage in upper-half casing provides lubrication to the packing area.

Shaft - (Steel) - Large - diameter, precision-machined, high strength steel shaft for maximum strength with minimum shaft deflection.

Bearing - (SKF) - High speed capability and low friction bearing.

Wear Ring - (Bronze) - A sacrificial component installed to inhibit fluid from re-circulating back to suction from the discharge.

Lantern Ring - (Stainless Steel) - A perforated hollow ring that receives relatively cool, clean liquid. Distribute uniformly around the shaft to provide lubrication and cooling.

Packing Gland - (Immersion Graphite) - flexibility allows the shaft to run freely as well as leak proof.

Stuffing Box (Gland) - (Bronze) - to press the packing gland into the seal area through bolts.

Plug - (Stainless Steel).

Bearing Housing - (Cast Iron).

Sealing Flush Line - (Stainless Steel) - Line from discharge of the pump and recirculated through the pressure regulating valve into the gland.

Water Slinger - (Oil Resistant Rubber).

Pump Coupling (ASTM No.35).
