Petrol Water Pumps

With such a wide image of pumps available and so many different requirements, trying to select the correct pump can be bewildering. Use the guide lines below to help you choose;

•  The first factor to consider is the quality of the water to pump. Clear water or water with very little sediment (such as swimming pool water) is known as clean water. Anything other than this, i.e. muddy ditchwater, dirty water with lumps of mud and debris etc is known as trash water.
•  However,  if the product to be pumped  is of a corrosive nature, such as liquid fertiliser, chemical substance,  salt water etc, you will need a corrosion-resistant pump, such as our HOS 2340.
•  The second major factor to consider is the required flow rate, which is how quickly you want to pump the water
•  The third point is the height of elevation. This factor is dependent  on the configuration of the installation and the application, e.g. pumping out, irrigation, drainage etc. It is calculated from;
•  The suction height – this is the difference in height between the level of the water to be pumped and the axle of the pump. Due to a law of physics, this difference in height cannot be greater than 8m.
•  The discharge height –this is the difference in height between the axle of the pump and the highest point of the installation (commonly the exit point of the discharge hose).
•  The head loss – this is the resistance encountered  bythe water in the pipes. It is calculated according to the length, diameter and quality of the pipes, their shapes and the number of accessories in use (filters etc).
•  Suction height + Height of lift + Head loss = Height of elevation
