The Series 'HA' is a heavy-duty, ANSI dimensional horizontal pump engineered for utmost reliability in severe chemical applications. The pump is machined from solid CPVC and utilizes an externally mounted mechanical seal. The 3x2x6 and 4x3x8 pumps have sleeved shafts for non-metallic solution contact while the 4x3x10 and 6x4x10 pumps utilize titanium or Hastelloy C shafts. This proven design provides excellent resistance to aggressive chemicals as well as economical and reliable operation for many years of service.

The Series 'HA' horizontal pump is available in four sizes with flow rates to 1200 gpm (3800 LPM), and is available with single or double mechanical seals and EPDM or FKM elastomers. Larger sized pumps designed to achieve 2400 gpm are in development. The standard configuration for these pumps is close coupled, however certain models are available long-coupled.

The Series 'HA' pump with its high flow rates, chemical resistance and durability makes it the perfect 'workhorse' for chemical processing, transfer and filter pumping, fume scrubbers and cooling towers or for waste treatment applications.

Pumps are machined from solid CPVC. 3x2x6 and 4x3x8 pumps have CPVC sleeved shafts while 4x3x10 and 6x4x10 pumps have titanium shafts standard with Hastelloy C shafts optional. Elastomers are FKM or EPDM. All models have an enclosed impeller, externally mounted Type 21 mechanical seal with silicon carbide seal faces and ANSI 150 lb. flange connections. External hardware not in solution contact is SS. Motor is painted with two-part epoxy paint.

Single or double mechanical seals are available depending on the application. A double, water flushed mechanical seal is recommended for solutions containing abrasives, high temperatures or other critical service applications.

The standard configuration for Series 'HA' pumps is close coupled, however 3x2x6 and 4x3x8 pumps are also available long coupled. Pumps 20 HP and above are mounted on a 36'x15' steel baseplate.
