Pump Selection
Selecting the correct pump for the task:
On our web site you are able to select and purchase nearly any pump on-line with your credit card and if you know how to select the right pump for the job, this makes purchasing very easy. If you are unsure or, if you have no idea which pump is the correct one for your application, we will happily assist you.
The table below provides a good indication of which pump will be the most suitable for your particular situation for a house supply pump. This table assumes that the water tank is above ground and that the pump is beside the base of the tank with less than 10m of pipe to the house. All of these pumps are Italian Made MH series pressure pumps or Grundfos CMBE series and have automatic on/off controllers that provide protection against running dry. Excellent quality with a proven track record in a quiet yet powerful automatic pump unit. A Grundfos pressure tank in your system will reduce the number of pump starts by up to 50% or even more, this saves money and extends the life of the system. An MH Series pump installed correctly on a house should last more than 15-25 years, dont forget to protect your pump from rain, sun and freezing.
The following flow rates are actual measured flow rates from within my house:
Kitchen mixer tap is 7 litres per minute,
Toilet cistern refil rate is 9 litres per minute,
Shower is 7 litres per minute,
Front loading washing machine is 8 litres per minute,
Dishwasher is 8 litres per minute,
So even with 2 showers, the washing machine and the dishwasher all going at the same time, the required flow rate is only 30 litres per minute.
