STjh four-pump 7.5 kW variable-speed cooling-water set on a long DN100 manifold skid on white.

STJH-COOLING-WATER-PUMP-SET-4X75KW

Cooling-Water Pump Set 4 × 7.5 kW Variable-Speed

A large four-pump variable-speed set with 7.5 kW motors, DN100 manifold and a 1750 mm-long base for staged N+1 service.

Four 7.5 kW pumps
1750 mm manifold length
Staged N+1 flexibility

Introdução do produto

This largest selected pump package carries four 7.5 kW vertical multistage stacks along a 1750 mm manifold. The four-pump arrangement supports wide turndown, staged capacity and N+1 operating flexibility for large cooling-water systems.

Características-chave

Four-pump operating range

Multiple small hydraulics divide a large variable flow across efficient staged combinations.

N+1 planning capability

One pump can be reserved while the remaining units cover the verified design duty.

Long serviceable base

The 1750 mm arrangement separates four motor and pump stacks for individual access.

Parâmetros técnicos

Motor Power Each	7.5 kW
Pump Type	Vertical multistage
Manifold Connection	DN100
Base Length	1750 mm
Control	Variable-speed multi-pump sequencer
Redundancy	N+1 capability when duty permits
Header Arrangement	Common suction and discharge manifolds
Installation	Large indoor utility skid
Customização	Duty combination, redundancy logic and manifold equipment can be configured for the intended application and operating environment.

Applications

Large cooling-water circulation, clean manufacturing utilities, central process loops and systems needing broad staged capacity.

Solutions for Your Application

The facility needs both high peak flow and efficient low-load operation.Sequence the four variable-speed pumps so only the number needed for current demand operates.

Service on one pump must not remove the whole plant duty.Reserve one hydraulic for N+1 service where the verified three-pump output covers design flow.

Opções disponíveis

Pump quantity control, stainless manifolds, pressure sensors, isolation, non-return valves, expansion vessel, metering and supervisory interface can be selected.
