I long accepted that there are different ways to achieve the same end and there are different products on the market. Competition is no bad thing as it keeps us striving to improve the Spring Pump controller and keeps prices keen. The origins of our pump controller go back to a conversation with a window cleaner probably 18 odd years ago. The issue he was having were. High water use. 2 Pump pressure switch regularly failing, Pump motor over heating and failing. Battery charge not lasting long.
A pump driven straight form a battery will draw around 7amps and hour assuming it is a 5,2 litre per minute pump running into 6mm hose actual flow to a brush is around 2.7 litres per minute this is due to the restriction created by the hose. 2.7 litres a minute is 162 litres an hour. As The pressure switch is under high load (7amps) when a tap is closed the pressure switch opens to stop the pump and that high energy arch,s across the switch burning it out.
The first pump controller V1 as we called it gave flow control over the pump meaning that the same amount of water could be used if needed But current draw dropped meaning that the battery charge lasted longer ( More time to work) People also found they could work just as effectively with less water on the glass. and flow rates were reduced. In a stroke the V1 meant both water and battery charge both lasted longer.
Next we look at protecting the pump pressure Switch and we introduced a Manual calibration. Now Rather than the pump pressure Switch opening under high load when flow stopped. The controller now stopped the pump well before the pump pressure switch needed to. The controller reduced load on the pump motor and pressure switch, reduced battery current draw ( without effecting the maximum flow) Giving flow control over the pump meant that water used could be varied to suit each work site. While using a tap can give variation of flow. The pump is still working flat out and working much harder than it needs to.
Controllers then Reduced current draw, prevented pump pressure switches burning out and gave the ability to suit flow to each job. The Pressure switch protection has been very effective and it is unusual these day for a pump pressure switch to fail.
Over time and through conversations with distributors and suppliers the controller have developed and we have added Battery voltage indication, Current sensing check, Electrical checks, Reverse polarity protection. The 4th Button on the new V16 is a result of requests from people using controllers as is the reverse polarity protection.
In all the years we have designed, tested and built the controllers in the UK, we give a 2 year return to base warranty. We look to provide support to those using the controllers directly and produce online and paper user guides and information and videos for installation all that is freely available.
In terms of Flow, pressure and battery current draw the following covers all these
