Well Pump Pipe Sizing

10 ppm in water for sprinkler irrigation systems.

Well pump pipe sizing.

15 ppm in water for flood irrigation. Define your application requirements. Based on the manufacturer s information the pump suction flange is eight inches in diameter 200mm and the pump discharge flange is six inches in diameter 150mm with the eleven inch 279mm indicating the pump s maximum impeller diameter. Poly pipe has the lowest pressure rating of about 250 psi.

Initially a new well will always produce some sand and silt and well development is the process of pumping a new well free from sand and silt. Use the required diameter of piping that is called for by the pump s manufacturer. But the pump sizing tool helps you find the information you need fast from application through to installation. Pvc comes next with 1 25 schedule 120 rated at about 600 psi.

What is required desired flow. The pump usually refers to both the pump itself and an electric motor which together make up the pumping unit. Friction loss total length x friction loss straight pipe factor friction loss fittings friction loss 922 x 1 8 100 3 x 2 1 8 100 friction loss 16 60 108. 5 gpm determine tdh first let s calculate friction loss.

Galvanized pipe is the best in higher pressures with 1 schedule 40 rated to about 2 100 psi and 1 schedule 80 rated to about 3 500 psi. Enter your duty point in the pump sizing software and choose to size by application. A 1 inch schedule 80 pipe is approximately 3 16 of an inch thick and a 2 inch diameter schedule 80 pipe is almost a full 1 4 inch thick. Video of the day.

The three pressure switch settings for pressure tanks are 20 40 30 50 and 40 60. This can range from 1 inch to 2 inches in diameter. The reason friction is given in ft per 100 ft of pipe is that the pipe length will be different in each application. The general rule is to never install a pump that has a greater capacity than your well.

How to size a pump. It sounds a bit strange to have friction in units of feet. The pressure switch setting is the pressure at which the pump turns on to fill the tank up and the pressure at which the pump shuts off knowing the tank is full. Let s say your pipe is 20 ft long then the friction is 18 x 20 100 3 6 feet.

Then select parameter for evaluation such as energy consumption and click start sizing.
