Chemflo® 1-Enclosed

Chemflo® 1-Enclosed

1-1/2" x 1" End Suction Centrifugal Pump with Enclosed Impeller

MP Pumps has re-designed the Chemflo® 1 housing allowing for the acceptance of both a semi-open and enclosed impeller. The enclosed impeller improves both the pressure capability and pump efficiency by 15% over the semi-open impeller making it an ideal option when pumping fluids without large solids. Maximum solids should not exceed .15 diameter.

All wetted components are 316 investment cast stainless steel providing superior corrosion resistance when pumping chemical compounds.  The Chemflo® 1 is adaptable for close coupling to both 56C and 145TC NEMA frame electric motors. Pedestal (Bare Shaft) mounting is available for long-coupling. The Chemflo® 1 is also available with the MP Hy-Speed hydraulic motor.

 If ordering a pumpak with a 145TC please note that the electric motor must have a base.
