Base mounted, back pull out design with flexible couple permits ease of service. Coupling shielded by a dual rated, ANSI B15.1, Section 8 and OSHA 191.219 compliant coupling guard and containing viewing windows for inspection of the coupling. This pump has two centrifugal impellers, back to back. Placement of the impellers balances the axial thrust and opposed discharges balances the radial thrust. The mechanical seal operates between the stages to prevent excessive wear.
