Description

The casing is designed for back pull-out which permits the removal of complete rotor unit without removing suction and discharge pipe. The cast iron volute casing is of robust design with integrally cast feet, vertical top centerline discharge with axial suction incorporating cast inlet vane to give best flow to impeller eye.

Driven end / non-driven end bearing are grease lubricated deep groove ball bearings.

Impeller is double shrouded type. It is hydraulically balanced and positively driven by shaft key and axially locked between sleeve and impeller nut.

Soft-packed stuffing box. Graphite impregnated type gland packing.

Ratings

Description

• Standardized design with reliable performance
• The cast iron casing is axially split which permits removal of the complete rotor without moving either piping or motor. Pumps generating high heads have double volutes to reduce radial forces, ensuring minimal shaft deflection and low bearing loads.
• The bronze closed type impellers have double curved vanes. The double suction design gives practically zero axial forces. Each impeller is statically and dynamically balanced.
• The carbon steel shaft is fully sealed against the liquid being pumped. Shaft protecting sleeves are fitted in the seal area.
• Replaceable cast iron rings protect the casing at the impeller running clearances.
• Stuffing box is fitted with mechanical seal. Pump can be supplied with gland packing also.
• Bearings are grease lubricated deep groove ball type.

Description

A jockey pump is a small pump connected to a fire sprinkler system to maintain pressure in the sprinkler pipes. This is to ensure that if a fire-sprinkler is activated, there will be a pressure drop, which will be sensed by the fire pumps automatic controller, which will cause the fire pump to start.

A jockey pump is sized for a flow less than the flow to one sprinkler in order to ensure a system pressure drop. Hence a jockey pump is an important part of the fire pumps control system.

Jockey pumps are typically small multistage centrifugal pumps, and do not have to be listed or certified for fire system application. The control equipment for jockey pumps may however carry approvals.

Description

Suction bell is furnished with an extra-long bearing that strengthens and provides rigid support for the lower end of the pump shaft. Suction bell provides efficient flow into the eye of the first stage impeller.

The rugged pump discharge head assembly is made of close-grained cast iron. It has smooth passageways that ensures efficient overall operation and provides an above ground connection to the discharge piping.

Impellers are enclosed type, made of bronze / SS 304 and matched to the pump bowls. Each impeller is statically / dynamically balanced as per ISO 1940-1 to insure highest efficiency and vibration free operation

Features

• Complete unit responsibility
• Complete in-house fabrication capabilities
• Hydrostatic strength testing facilities.
• Operation run test as per NFPA 20, UL 448 requirements.
• Vertical turbine models for capacities from 50 to 1500 US GPM
• Drivers: Electric motor drive or diesel engine drive.
• Electrical testing capabilities for motors and controllers as per NFPA standards.
• Capable to supply additional accessories wherever required.
• Rugged construction for longer service life.
• Specifically designed for firefighting applications as per NFPA 20.
• Excellent mechanical and hydraulic design characteristics for efficient performance.
