Features
Removable Rotating Assembly
Inspection of pump shaft or bearings is easily accomplished without disturbing pump casing or piping by removing rotating assembly. Simply remove four bolts from the back of the pump and the assembly slides out. This allows for quick and easy installation of a spare rotating assembly, resulting in less downtime.
Abrasion-Resistant Mechanical Seal
Double-floating, self-aligning oil lubricated mechanical cartridge seal with stationary and rotating face of silicon carbide is specifically designed for abrasive industrial wastewater service.
Solids Handling Impeller
Two-vane, semi-open, solids handling impeller handles up to 3" (76 mm) diameter solids, depending on pump model. Pump out vanes on impeller shroud reduce foreign material buildup behind impeller and reduce pressure on seal and bearings for extended pump life.
External Shimless Adjustment
The external shimless cover plate allows for easy adjustment of the clearance between the impeller and the wearplate. This process eliminates the need to realign belts, couplings or other drive components. In turn, the working height of the seal assembly and impeller back clearance are not disturbed. The unique collar and adjusting screw allow for incremental adjustments of the wearplate clearance with the turn of a hand. Once adjustments have been made, the collar locks in place maintaining the clearance setting even if the cover plate is removed. This design doubles the life of the impeller and wearplate, and keeps the pump operating at maximum efficiency.
Durable bearing protection
An atmospheric barrier and two lip seals provide protection of the pump bearings. This allows for quick and easy external monitoring of the bearing cavity.
Replaceable Wearplate
PST Series pumps feature replaceable wearplates which fasten to the cover plate and can easily be removed for inspection or service. No expensive castings to replace.
Drive Variations
PST Series Pumps are available as basic units for connection to customers' power source or may be flex-coupled or V-belt driven by an electric motor. Pumps may also be powered by gasoline or diesel engines. Electric motor driven pumps with "standby" engine power are also available.
