Description
The Pentax CM100/61 230v (code 022-120) is a single impeller centrifugal pump for clean water at higher pressure. It reaches a maximum head of 33 metres and delivers up to 90 litres per minute from a 0.74 kW (1 hp) motor, through a 1″ threaded outlet, running on 230v single-phase at 5.7 A.
The CM100/61 is the most powerful single-phase pump in the set. Pentax gives it 31.5 metres at 40 l/min, 29.6 metres at 60 l/min and 25.2 metres at 90 l/min, against 12.0 metres from the Pentax CM50 230v at the same flow. If you have a three-phase supply and need more, the Pentax CMT 214 400v reaches 50 metres and 120 l/min.
Like the CM50 it has a 1″ threaded inlet and outlet. The pump body is cast iron, the motor bracket is aluminium, the motor shaft is AISI 416 stainless steel and the mechanical seal is ceramic and graphite. The two-pole motor has class F insulation, and Pentax rates the pump for a maximum operating pressure of 6 bar.

For clean water only. The CM100/61 is not designed for dirty water, solids, sewage, or flammable or corrosive liquids, and it must never run dry. It is not self-priming, so install it with a flooded suction or a foot valve. It has no pressure switch, so it runs whenever power is applied; add a suitable control for automatic boosting. It comes with a Noryl impeller as standard, which limits the liquid temperature to 50 °C.
