It is very important to purchase a pump specifically designed for WFP work.
The ideal pump is between 60 and 95 PSI with a delivery of 1 litre per minite per pole being used.
The exact PSI is down to a matter of choice of the individual user.
ShurFlo and FloJet both make pumps designed for window cleaning.
