NPSH. Close coupled motor pump with cast iron casing and bronze

impeller. Stainless steel shaft and Crane mechanical seal.

3 400 or 2 800 rpm motor suitable for 380 - 440 volt 3 phase 50 Hz or

60 Hz supplies. TEFV IP55 enclosure with Calss 'F' insulation utilizing

Class 'B' temperature rise only.

Control gear

Installation

The pump suction pipework incorporates a resilient coupling,

avoiding expansion stresses and facilitating pump removal.

A 1" BSP bronze non-return valve is fitted to the pump delivery.

Installation requires only connection of the inlet, vent, overflow and

discharge pipework, and wiring between the customers supply isolator

and the control gear enclosure. With the selector turned to 'Auto'

the unit operates to match demand with no further attention.

Note: It is recommended that a valve should be fitted in the delivery

pipework adjacent to the unit. Should the system head be less than

the unit head, the valve may then be adjusted to increase the

system head, reducing possible cavitation and noise.
