The Rainsaver MK4e replaces all changeover devices including the Davey Rainbank and Onga Waterswitch and converts manual pumps to a fully automatic mains and tank water changeover device in a jiffy. The changeover device is suitable for mains and pump flows up to 100 litres per minute and mains and pump pressure of 800kPa. The MK4e is suitable for pumps up to 1.1kW running on a 240V system and includes a plug and play power connection. You will still require to buy a pressure controller when replacing a Davey Rainbank and Onga Waterswitch, as these units have them built in. If the change-over device you are changing has a separate pressure controller that is functional, then you will not require a new pressure controller.
The pump is characterised by:
Corrosion resistant pump components.
Fully automatic operation.
Silicon Carbide mechanical seal.
240V single phase motor with in-built auto reset thermal overload.
10m of power cable.
Not suitable for construction sites, ponds, fountains or bio-treatment.
Flows to 83 l/m
Heads to 30m
Maximum particle size 0.5mm
Aesthetically designed and requires no weatherproofing.
Barrel Unions and “Torque Set” safety spanner are included to facilitate ease of servicing and to avoid tool damage or over tightening
UV Stabilized technopolymer for long life and good looks
All Rainsaver MK3e pumps are independently controlled to regulate flows and pressures whilst protecting the pump against voltage fluctuations, loss of water and incorporate a 24-hour automatic pump restart
WATERMARK approved for connection to all Towns Water supplies – Safe against waterborne bacteria, dezincification and lead poisoning
Auxiliary outlets allow for energy saver water storage – pressure vessels to reduce pump starts
Revolutionary “Mono Channel” design does not restrict flow or reduce pressures, eliminates any possibility of water leaks
12-volt low voltage flow switch with counterweight and mozzie stopper ensures total reliability and safety within 10m cable.
