Horizontal Split Case HVAC Pumps, 1800 RPM, 1200 RPM
(12 reviews)EnviroFlo Horizontal Split Case Pumps offer a high-efficiency design that minimizes energy consumption for a more Green sustainable HVAC system. And they are easy to service without disturbing piping connections. Just flip the lid on the HSC pump and you have a clear view of the entire rotating element, making it easy to service internal components.
Patterson engineers have shortened the distance between inboard and outboard bearings on these pumps to reduce the cantilever effect on the pump shaft and cut deflection at the seal faces. This results in long seal and case ring service intervals. Pumps are also delivered with standard silicon carbide mechanical seals or tungsten carbide, optional.
Standard regreaseable ball bearings are set in integrally cast bearing housings. Bronze fitted construction, with replaceable bronze shaft sleeves, is also standard; an optional stainless steel shaft and sleeve are available. A precision-cast, dynamically balanced bronze impeller minimizes vibration and maximizes bearing life.
EnviroFlo HSC pump bodies are formed from Class 30 cast iron with a carbon steel shaft (stainless steel is optional). Designed to deliver energy efficient flows to 6,000 gpm with heads to 160 ft tdh, these pumps offer standard case working pressure at 175 psi; optional 250 psi is available on select models. Gauge taps at the suction and discharge connections give complete monitoring flexibility.
