Hi, after some delay my new pool has finally been installed but I need some advice on equipment selection and setup. My pool is a small one only a 3m x 5m 15000L one loacted in Perth Western Australia so a temperate climate. Its a chlorine pool with an auto dosing unit including acid as well (chemigem system).
I have Viron EvoP320 pump with a cyclone pre filter going into a Davey 25 inch sand filter. I am trying to get the most bang for buck from the 3 speed pump whilst keeping the pool clean. In the manaul for the sand filter it details the max flow rate and min backwash flow rate but it doesn't mention the min flow rate when in filter mode. I am trying to run the pump at low speed, approx 1450 rpm which notionally gives 140lpm according to manual, will this be enough for the sand filter?
Second question, I have seperate piping (suction and return) for a pool heating system and have purchased a heat pump (swimtek 8kw) and am looking for a suitable circulation pump. Ideally I want the quietest and least power hungry pump I can get, does anyone have any reccomendations?
Third question, how is the circulation pump for a pool heat pump system that is seperate to the filtration circuit typically controlled/actuated?
Cheers in advance
