Single-stage, horizontal centrifugal pump on a base plate for firefighting water supply according to EN 733 and EN 12845.

Features:

With axial suction connection and radial discharge connection.
Pump with pump support foot and flanged bearing bracket, with spacer coupling and coupling guard.
Housing made of grey cast iron, shaft made of stainless steel, impeller made of bronze and neck ring made of stainless steel. All cast iron components in contact with the fluid are cataphoretic coated as standard.
Shaft sealing with bidirectional bellows mechanical seal.
With bypass valve as standard, mounted directly on the pump housing, to prevent overheating when the flow rate is too low.

Drive:

IEC electric motor, pre-assembled on the base plate of the pump.

NOTICE

The spacer coupling is an elasticated coupling with a spacer. The spacer reduces maintenance costs and no further motor alignment is necessary when replacing the mechanical seal.
