Flint and Walling 27 gpm 3/4 hp submersible pump is ideal for a well between 20' and 60' deep. Since you pump water from the static water level, which is the distance from the well top down to the water, at 30-50 pressure switch setting the 3/4 hp 27 gpm submersible pump will produce between 25 gpm at 40 psi at 20' of total lift, and will still deliver 18 gpm at 60' of depth at 40 psi, if the water level ever draws down to there.
When sizing your pump wire, you need to take the distance from the power panel where the meter supplies the power, out to the well, and down to the submersible pump in the well. With the 3/4 hp submersible pump set at 60' depth and a run to the main power panel of 150' you size your pump cable wire for 210' total run to the 3/4 hp motor. With the 3/4 hp 230V single phase motor running 210' total, we would need to run #12 wire to the pump. The #12 pump wire can run up to 480' total with the 3 hp pump motor.
When sizing a
water pressure tank for use with
the 3/4 hp 27 gpm pump, you should select a
bladder type pressure tank that
has a minimum draw down of 25 gallons. This way you prevent short cycling
the pump, because when it turns off, the pump can rest for 1 full minute
before turning back on. If we use a 30-50
pressure switch on the
tank fitting kit, we would need to select a minimum size water pressure
tank of AT244 which gives you 25.1 gallons of draw down, usable water from
the tank before the pump turns back on. A larger
pressure tank is OK if you
desire, as it will increase the usable water between pump cycles.
