Wine pumps and rousers

Italian (centrifugal type) pumps:

   stainless steel body, plastic rotor, up to 3600 litres/hour, 220 volt, with extra
                     fittings: 1" male thread inlet, with ball-valve fitted to outlet (ending in 1" male thread)
                     for speed control, £225

stainless steel, up to 1800 litres/hour, with internal bypass to reduce the flow,
220 volt, ¾" male threads and 19mm polypropylene hose-tails, £285
This has a nice slow and controllable speed.
Viton seals can be fitted, for pumping cleaning solutions or liquids at over 100 °C, £23 extra

bronze, up to 1800 litres/hour, with bypass, 220 volt, 19mm hose-tails, £115

Option for these three pumps: painted steel wheeled-trolley to mount the pump on, £26

Mohno (eccentric screw) pumps: very highly recommended, having the smoothest flow, they are equally suitable for filtration/bottling of wine or pumping cloudy juice (with suspended solids).
Some models can also pump destalked grapes.
Parts in contact with the juice/wine are stainless steel except for the neoprene stator. All have 380 volt (3 phase) electrics, single speed or 2-speed or variable speed motors, switchable to pump in either direction:-

Kiesel (or CAJ): made in Germany:-

SP04 M02 0.7/1.1 kW, 700/1400 rpm, up to 1250/2500 litres/hour (reduceable with bypass), 1350 Euros

SP45 M02 0.7/1.1 kW, 700/1400 rpm, up to 2500/5000 litres/hour (reduceable with bypass), 2057 Euros
SP45 M03 1.1 kW, variable speed motor 200-1400 rpm, 700 to 5000 litres/hour, 2626 Euros
SP45 M05 1.1 kW, frequency regulated motor, 300 to 5000 litres/hour, with bypass, 2626 Euros

SP04 and SP45 pumps have DN32 male threads, adaptors to 32-Mainz or NW40 @ 125 Euros extra

SP05 M02 1.0/1.9 kW, 700/1400 rpm, to 5000/10,000 litres/hour (reduceable with bypass), 2640 Euros
SP05 M03 2.2 kW, variable speed motor 200-1400 rpm, 1500 to 10,000 litres/hour, 3520 Euros
SP05 M05 2.2 kW, variable frequency motor, 800 to 9,000 litres/hour, 3520 Euros

SP05 pumps have DN65 male threads, adaptors to DN40 @ 175 Euros extra

Protection against dry running (stops the pump if there is no liquid): 485 Euros extra

Replacement stators: SP04 70 Euros; SP45 92 Euros; SP05 120 Euros

Variable Speed Drive / frequency regulated: controls/reduces the rotation speed of the pump and hence the throughput, an external unit that you can simply plug in to:-
   up to 1.1 kW 3-phase 400V, 1144 Euros
   up to 2.2 kW 3-phase 400V, 1290 Euros
   up to 3.0 kW 3-phase 400V, 1580 Euros
   up to 5.5 kW 3-phase 400V, 2000 Euros

Rubber-impeller pumps: Theo Schneider

Air-operated Diaphragm pumps:

Air diaphragm pumps are multi-use, safe and easy-to-use pumps. They run on compressed air rather than electricity and move wine via the compression and expansion of membranes, or diaphragms, inside the pump housing. These pumps are very gentle, can have a valve closed against them (advantageous when filling barrels) and can create enough head pressure to move wine uphill, though a sheet filter or across great distances. Some claim that they are not good for moving mash, but others say they're some of the best pumps for moving juicy mash because they don't chew up seeds and skins like rubber-impeller pumps can. They may not work well for dry de-stalked mash, but they are good with all other tasks and especially must pump-overs. The winery needs to have a compressed air system.

Bypass:

If the pump does not have a bypass built in then you can make one by fitting a T-piece each side of the pump, with a connecting tube between them. If the pressure builds up on the outlet side, then the liquid will flow back (re-circulate) around this tube.
