• General purpose pumping

FEATURES

Compact Design
Close coupled, space saving design provides easy installation. Flexible couplings and bedplates not required.

Mounting
Can be mounted in vertical or horizontal position.

Construction
Available in bronze fitted (BF), all iron (AI), or all bronze (AB). Bronze fitted means bronze impeller.

Impeller
Enclosed design for high efficiencies. Threaded directly on motor shaft. Stainless steel locknut on three phase models requires no clearance adjustments. Balanced for smooth operation.

Casing
