Close-Coupled End Suction HVAC Pumps
Close-Coupled Configuration
Patterson close-coupled end suction HVAC pumps offer a high-efficiency design that minimizes energy consumption, and their back pullout configuration provides easy access and simplifies maintenance.
Benefits/Features
- Gauge taps at the suction and discharge connections for complete monitoring flexibility
- Annular pressure reducing clearance with impeller balance holes to reduce axial thrust
- Precision-cast, dynamically balanced impeller minimizes vibration and maximizes bearing life
- Precision bearings and shaft design limit deflection at the seal face
- Standard case wear ring
- Mechanical seal is standard in carbon vs. silicon carbide (optional: tungsten carbide) with an external seal flush line
- Every pump hydrostatically pressure-tested
- Optional 250-lb discharge flanges on many models
- Standard construction with bronze shaft sleeve and steel shaft; optional stainless steel sleeve and shaft available
- Optional rigid mounting base
