Construction & Features:

• Design: Close coupled, space-saving design -- no flexible coupling or bedplate required. Can be mounted in vertical or horizontal position.
• Casing: Bronze, ASTM B584 C87500 (lead-free), volute type, back pull-out design; discharge can be rotated in eight positions (standard vertical shown); tapped openings for priming, venting, and draining
• Impeller: Bronze, ASTM B584 C87500 (lead-free), enclosed design for high efficiency, threaded directly onto the motor shaft, balanced for smooth operation. Stainless steel impeller locknut on three-phase models requires no clearance adjustments.
• Adapter: Bronze, ASTM B584 C87500 (lead-free)
• Shaft: Stainless steel motor shaft carries the impeller directly (no separate pump shaft)
• Mechanical Seal: Standard carbon/ceramic faces, BUNA-N elastomers, 300 series stainless steel metal parts (Seal Type 6, P/N 10K10); optional Ni-Resist, EPR, and Viton seal configurations available for elevated temperature or chemical service
• Motor: NEMA standard, close-coupled design; ball bearings carry all radial and axial thrust loads; designed for continuous duty within the motor's working limits. Overload protection and heaters must be provided in a separately ordered starter unit.

Applications: Water circulation, booster service, liquid transfer, spraying systems, jockey pump service, and general purpose pumping.
