North Ridge Industrial Heavy-duty Flexible Impeller Pump

RF Industrial Heavy-duty Flexible Impeller Pumps

Our RF pump range is available in three metal casting materials; GG20 cast iron, RG10 bronze and AISI -316 stainless steel, this range of industrial heavy-duty flexible impeller pumps is mostly used for food transfer and chemical transfer applications, due to their smooth pumping action and non-pulsating flow, these pumps are an ideal solution for handling sheer sensitive food products such as milk, cream and mayonnaise.

These flexible vane pumps have fantastic self-priming capabilities, they can achieve a suction lift of up to 6 metres from dry. There are four models available in the RF range, covering a flow rate of 28 – 350 l/min (1.68 – 21 m³/h) and a max. head of 20 metres. The RF range can be supplied with either Neoprene or NBR (Nitrile) rubber impellers and are available with ATEX (explosion proof) motors, meaning they are suitable for handling flammable liquids such as alcohols.

The RF flexible impeller pumps can handle viscosities up to 20,000 cp and a max. liquid temperature of 70 °C, RF pumps are fully reversible, these pumps can be supplied in several different configurations such as trolley mounted with on/off and reversible switch, meaning the inlet of the pump can become the discharge by simply flicking a switch, making the RF pump range an excellent solution for transfer applications in general.
