Speroni KF(M) Industrial Peripheral Pump

Speroni KFM Peripheral Pump | Cast Iron Pump for Industrial Pressure Boosting and Boiler Feed

The Speroni KF(M) is a cast iron peripheral pump designed for light industrial pressure boosting, boiler feed from stored water, and small circulation loops. Peripheral pumps use a regenerative turbine impeller that carries water around the pump body several times before discharging, adding pressure with each pass. This gives the KF(M) a high head output from a compact, low-power motor. Four models are available across 230V single phase and 400V three phase, all with 1 inch inlet and outlet ports.

What is the Speroni KF(M) Industrial Peripheral Pump used for?

•    Pressure boosting from a stored water tank (non-potable applications)
•    Boiler feed from stored water (not for direct mains connection)
•    Light industrial pressure boosting in small circulation loops
•    Non-potable welfare units and portable or temporary accommodation
•    Auto-trigger booster systems with an optional pressure controller
•    Light industrial processing and water transfer

Construction and Durability

The KF(M) is built from cast iron with a brass pump body cover, which distinguishes it from the KP(M) and makes it more commonly specified for industrial and boiler feed applications. The regenerative turbine impeller delivers high head on small motors by recirculating water multiple times before it exits the pump. An optional pressure controller adds dry-run protection and automatic start/stop on demand.

Why choose the Speroni KF(M) Industrial Peripheral Pump?

Where a centrifugal pump would struggle to deliver adequate pressure from a small motor, the peripheral design of the KF(M) builds head efficiently by recirculating the water multiple times through the impeller before it exits. This makes it well suited to boiler feed and boosting duties where sustained pressure matters more than high flow. The brass pump body cover and cast iron construction give it good service life in light industrial environments, and the 1 inch ports on all models keep installation straightforward.

Operational Details

•    KFM1 (230V single phase): 0.37 kW
•    KFM2 (230V single phase): 0.6 kW
•    KF1 (400V three phase): 0.37 kW
•    KF2 (400V three phase): 0.6 kW
•    Inlet and outlet: 1 inch BSP on all models
•    Pump body: cast iron with brass cover
•    Not self-priming: requires flooded suction (water source at or above pump inlet)
•    Not WRAS approved: not suitable for drinking water supply
•    For self-priming applications, see the Speroni AKM60

The Speroni KP(M) has a different internal layout and is often specified for light circulation duties. 

Optional Accessories

A pressure controller can be added to provide dry-run protection and automatic start/stop when demand occurs. This turns the KFM into a simple automatic booster unit.

Important: WRAS Approval

This pump is not WRAS approved and is not for drinking water supply. It is suitable for irrigation, sprinklers, fire systems, rainwater harvesting, cooling loops, and industrial or agricultural water.
