M

3P hollow rotary disc positive displacement pump, M series: a single eccentric rotating and oscillating hollow disc gives smooth, quiet, self-priming operation at low speed with constant capacity even when rotation is reversed. For medium, high and very high viscosity fluids with small suspended solids. Flow rate 0.3 to 100 m³/h, pressure 8 bar (12 or 20 bar optional), viscosity up to 200,000 cSt, temperature up to 280 °C, up to 500 rpm, port sizes DN 25 to 150.
