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.

Italian pumps:-

   JIM G5: 219.00
up to 3600 litres/hour, 230 volt, 370 Watt, AISI 304 stainless steel body, AISI 316 shaft,
   plastic rotor, 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 slower pump:-

   ALM 20: pump body, impeller and shaft all AISI 316 stainless steel, 352.00
                             1800 litres/hour
, 230 volt, with internal bypass to reduce the flow,
                       " male threads and 20 mm polypropylene hose connectors,
                       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 over 90 C, 27.50 extra

for the above pumps: wheeled-trolley to mount the pump on.
