Pipe Tapping Sizes

Motor Approx.

with multi-port, precision-molded,
reinforced polypropylene diffuser.

Mechanical Shaft Seal – Precision
lapped and highly polished carbon­ceramic, stainless steel construc tion.
Internal design guarantees contin­uous water lubrication.

Motor Windings – Superior insula­tion materials protect against exces­sive moisture and contaminants…
assure prolonged motor life.

Balanced Rotor – Die cast under
high pressures for uniform perfor­mance and greater efficiency,
dynamically balanced.

Heavy-duty Ball Bearings –
Shielded, permanently lubricated
bearings, extensively tested to
ensure extended life and smooth,
quiet operation.

Pump and Motor Shaft –

steel for maximum corrosion resis­tance; one-piece threaded shaft for

positive impeller drive and alignment.
Dustproof Cover – All electrical

components are protected from dirt,
dust and insects by a dustproof
canopy; ventilating air cannot con ta­m i nate vital switching components.

Pressure Switch – Professional

Pump will operate at all depths shown, with pressure switch set at
30-50 PSI.

Tested and rated in accordance with Water Systems Council Standards.
NOTE: Pumps installed with a PRO-Source™ tank require a 100 PSI relief

valve. Pumps installed with a conventional tank require a 75 PSI
relief valve. Relief valve must be capable of relieving entire flow
of pump at relief pressure.
