Winegrowers Supplies - Pumps (centrifugal type)
Notes: the internal diameter of your hose must be large enough that excessive turbulence does not occur in the flow:-
20 mm internal diameter, up to 3500 litres/hour,
25 mm internal diameter, up to 5700 litres/hour,
32 mm internal diameter, up to 8600 litres/hour,
38 mm internal diameter, up to litres/hour,
50 mm internal diameter, up to litres/hour,
60 mm internal diameter, up to litres/hour.
Where pump speeds are stated (litres/hour), this is the maximum, at zero pressure.
The speed reduces as pump-head-height increases, typically 5000 litres/hour
would reduce to 3000 litres/hour at 2.0 bar pressure.
A bypass, where specified, will allow speed to be reduced and provide pressure control.
Novax pumps, stainless steel housing and impeller, 230 volt. Liquids must contain only very small particles, temperature up to to 35 °C:-
M20: connectors for 20 mm id hose, up to 1700 litres/hour, 2850 rpm, 0.37 kWatt, 5 kilos, £102
M20 with bypass: connectors for 20 mm id hose, up to 1700 litres/hour, 2850 rpm, 0.37 kWatt, 5 kilos, £129
M20B for beer up to 95 °C: connectors for 30 mm id hose, up to 1700 litres/hour, 2850 rpm, 0.37 kWatt, 5 kilos, £112
M25: connectors for 25 mm id hose, up to 2400 litres/hour, 1450 rpm, 0.45 kWatt, 6 kilos, £132
M30: connectors for 30 mm id hose, up to 5000 litres/hour, 1450 rpm, 0.75 kWatt, 10 kilos, £219
up to 3600 litres/hour, 230 volt, 370 Watt, AISI 304 stainless steel body, AISI 316 shaft, 1" bsp threads,
plastic impeller, maximum liquid temperature 60 °C, max 6 bar pressure, max 8 metres pump-head-height.
optional bypass with stainless steel hose-tail-connectors to 20 mm id hose, it works very well:-
or a pump for higher temperatures:-
ALM 20: pump body, impeller and shaft all AISI 316 stainless steel, £359.00
up to 1680 litres/hour, 230 volt, with internal bypass to reduce the flow,
¾" bsp male threads and hose connectors for 20 mm internal diameter hose,
maximum liquid temperature 90 °C, max 6 metres pump-head-height,
This has a nice slow and controllable speed. It has high self-priming capability.
It is noisier than other pumps, especially with the bypass open.
The switch enables flow in either direction. IP44 motor protection.
Viton seals can be fitted, for pumping cleaning solutions or liquids at up to 130 °C, £32.50 extra
Option for the above pumps: wheeled-trolley to mount the pump on.
