Main Types of Pumps • Clean Water – Centrifugal Pumps • Sewage / Storm Water – Centrifugal Pumps • Chemical Metering – Diaphragm Pumps
End Suction End suction pumps can be mounted horizontally or vertically. These pumps are utilized generally for low to medium head applications. Shut off head pressures are not normally a problem with this type of pump.
Horizontal End Suction Pumps Close Coupled Flex Coupled
Typical Break Tank System Duplex Pump Arrangement Galvanized, Epoxy-coated Steel Tank Fiberglass Hydro-pneumatic Tank
Split Case Split case pumps are available in both horizontal and vertical configurations. They are most common on high capacity applications. Shut off head pressures are generally not a problem with this type of pump.
Non-clog SubmersibleSewage Pump A. Motor - Oil filled to efficiently dissipate heat and lock out damage moisture so you receive reliable pumping service. B. Connection Box - Two epoxy barriers and a compression fitting prevent water contamination of the motor area assuring long-term reliable operation. Additionally, epoxy encapsulation and stripped leads positively eliminate “wicking” from the cable. C. Bearings - Heavy-duty ball bearings, upper (radial) and lower (thrust), are submerged in oil to provide permanent lubrication and ensure long service life. D. Seals - A dual seal system operates in an oil chamber to provide long pump service life. J.C. Type 21 seals are standard and readily available - optional materials upon request. E. Shaft - The stainless steel shaft eliminates corrosion and fatigue to give longer pump life. The minimum shaft overhang decreases deflection and increases bearing and seal life. Tapered shaft allows for easy removal of impeller. F. Impeller - Two vane non-clog impellers provide the most efficient design. Pump-out vanes on the top shroud prevent the build up of materials in the seal area and extend the life of the thrust bearing by significantly reducing axial thrust. G. Renewable Case Wear Ring - Reduces maintenance costs while maintaining the performance of the pump.
Self-Priming Systems • Advantages: • Quick Clean Out • Easy Maintenance • Low Installation Cost • Close Coupled Design
