WHY IT WORKS

Built for the job

Cast iron single-stage centrifugal pump for general clean water transfer, the core Speroni centrifugal workhorse.

The C(M) is Speroni Pumps’ core single-stage centrifugal pump. A wide range of models covers almost every standard transfer and circulation application, which is why this pump appears on more pricelists than almost any other in the Speroni catalogue.

Single-stage means one impeller. The pump is simple, reliable, and easy to service. It handles clean water across a wide flow and head range, and the sheer number of model variants means there is almost always a C(M) that matches a specific requirement exactly.

Where the Speroni C and CM Pumps are Used

Agricultural transfer and irrigation.
Industrial process water circulation.
Cooling and mixing duties.
Filling and topping up water systems.
General clean water supply on non-potable systems.
Water transfer between tanks.

Choosing Between the Models

The range is organised by motor frame size. Bigger frame means bigger pump means more flow. Within each frame, the motor power determines the head. For help choosing, tell us the flow you need and the head you need to develop, and we will point you to the right model.

M = 230V single-phase, no M = 400V three-phase.

C(M) Versus CF(M)

Both are cast iron single-stage centrifugal pumps. The split is by flow rate.

C(M) suits smaller jobs (agricultural, small industrial).

The Speroni CF(M) steps up to heavier industrial and large agricultural duties. If your flow requirement is modest, the C(M) is the right answer.

Not Self-Priming

The C(M) is not self-priming. It needs flooded suction or a primed foot valve on the suction line.

They are designed for pumping clean water only in many domestic, and agricultural applications, and industries. Has a maximum suction of 7 metres.

Common questions

Can the Speroni C(M) centrifugal pump handle dirty water?

No, the C(M) is designed for clean water only. Typical uses are agricultural transfer and irrigation, industrial process water circulation, cooling and mixing duties, filling and topping up water systems, and transfer between tanks on non-potable systems. For water that is slightly dirty, the open-impeller Speroni GA(M)100 is the alternative; neither is a drainage or sewage pump.

See: Speroni GA(M) 100 Single-Stage Centrifugal Pump

Is the C(M) self-priming? Do I need a foot valve?

No, the C(M) is not self-priming. It needs flooded suction, with the water level at or above the pump inlet, or a primed suction line with a foot valve. With a foot valve the maximum suction lift is 7 metres. Fill the pump and suction line with water before starting, and keep all suction joints airtight.

See: Brass Foot Valve & Stainless Strainer

Which C(M) model gives the flow and head I need?

The range is organised by frame size. The C(M)22 to C(M)32 give up to 100 to 125 litres per minute at 20 to 29 metres head. The C(M)35 to C(M)53 give up to 140 litres per minute at 36 to 53 metres. The C(M)54 and C(M)55 give up to 360 litres per minute at 46 and 56 metres. Within each frame, more motor power gives more head.

What is the difference between the CM and C models?

An M means 230V single phase, for a normal domestic or workshop supply; no M means 400V three phase, for farms and industrial sites with a three-phase supply. Every C(M) size, from 0.37 kW up to 4 kW, is offered in both versions with the same performance. The C(M)22 to 32 have IP44 motors and the C(M)35 to 55 IP55, all Class F.

What hose or pipe sizes fit the C(M)?

The C(M)22, 27 and 32 have a 1 inch BSP female inlet and outlet. The C(M)35, 45 and 53 have a 1¼ inch inlet and 1 inch outlet. The C(M)54 and 55 have a 2 inch inlet and 1¼ inch outlet. Size non-collapsing suction hose or pipe to your model's inlet (25mm, 32mm or 50mm), with a foot valve and strainer if the water is below the pump.
