Installation 5

DRIVEN POINT INSTALLATION

Step 1. Connect suction pipe to drive point (Fig. 2). Keep

horizontal pipe run as short as possible. Use

Teflon tape on male pipe threads. Multiple well

points may be necessary to provide sufficient

water to pump.

Step 2. Install check valve in horizontal pipe. Flow arrow

on check valve must point toward pump.

HORIZONTAL PIPING FROM WELL TO PUMP

Step 1. Pump performance will be decreased if less that

1-1/2" pipe is used as suction pipe.

Step 2. To aid priming on well point installations, install

line check valve. Be sure check valve flow arrow

points toward pump.

DISCHARGE PIPE SIZES

Discharge pipe size should be increased to reduce pres-

sure losses caused by friction on long pipe runs.

• Up to 100' (30.5 m) run: Same size as pump dis-

charge port.

• 100' - 300' (30.5 - 91.4 m) run: Increase one pipe

size.

• 300' - 600' (91.4 - 182.9 m) run: Increase two pipe

sizes.

LAWN SPRINKLING APPLICATION

This pump is designed for lawn sprinkling. Delivers plen-

ty of water at full sprinkler pressure. Pumps from pond,

cistern or well points.

Pump discharge can be divided to supply 4 or more

sprinkler systems.

Do not use in booster pump applications.

PUMP/PIPING INSTALLATION

If turning pump on and off by pressure, a pressure switch

and tank are required. For proper installation and opera-

tion instructions call Customer Service.

Use rigid pipe. Do not use hose or plastic tubing. See

“Well Pipe Installation” for more information.

NOTICE: Use only Teflon tape or Teflon based joint com-

pounds for making all threaded connections to the pump

itself. Do not use pipe joint compounds on plastic

pumps: they can react with the plastic in pump compo-

nents. Make sure that all pipe joints in the suction pipe

are air tight as well as water tight.

If the suction pipe can

suck air, the pump will not be able to pull water from

the well.

Step 1. Bolt pump to solid, level foundation.

Step 2. Support all piping connected to pump.

Step 3. Wrap 1-1/2 to 2 layers of Teflon tape clockwise

(as you face end of pipe) on all male threads

being attached to pump.

Step 4. Tighten joints hand tight plus 1-1/2 turns. Do not

overtighten.

Step 5. Replace prime plug with pressure gauge. This

will aid in sizing zones, troubleshooting, and fol-

lowing pump performance chart.

NOTICE: Install pump as close to well head as possible.

Long piping runs and many fittings create friction and

reduce flow.

NOTICE: For long horizontal pipe runs, install a priming

tee between check valve and well head (Fig. 1). For dri-

ven point installations, install check valve. Be sure that

check valve flow arrow points toward pump.
