Schurco P Series are designed to provide exceptional performance in high head mine dewatering as well as general dewatering applications.
Single pumps can achieve heads over 50% higher than standard slurry pumps. These dewatering pumps are ideal for dirty water and light slurry (slurry-specific gravities of roughly 1.05), and provide the end user with the ultimate in reliability.
Impeller – Double volute design to reduce radial loads, and thrust reduction impeller design to reduce axial thrust loads, thus enhancing bearing life.
Casing – Wet-end components are manufactured in wear-resistant alloys to suit the application, providing these pumps with unique wear advantages over many similar pumps on the market.
Expeller (Centrifugal Seal) – no external sealing water required where applicable
Stuffing Box – flushed gland sealing with braided packing and a lantern ring
Mechanical Seals
Cartridge-style bearing housing allows for removal from pump and assembly in controlled environment
Oversized shaft diameters and reduced overhang in the wet end contribute to long life and reliability in the field
Oil bath lubrication for higher operating speeds against the standard grease lubrication in other assemblies
Designed for front pull-out or back pull-out dismantling of the frame and shaft assembly from the casing, which remains in place, connected to the intake and discharge pipework. This enables a rapid replacement of frame and shaft assembly with a standby unit, while leaving the pipework undisturbed.
The stuffing box is the original shaft seal for any rotating element through a fixed device. This seal has stood the test of time, and is still one of the most common sealing arrangements in slurry pumps. Seal water must be supplied at a pressure in excess of pump discharge pressure.
A mechanical seal consists of two principle components. One component is stationary and the other rotates against it to achieve a seal. There are many types of mechanical seals, ranging from simple single spring designs to considerably more complex cartridge seal types, which are the type most commonly applied on slurry pumps. The design, arrangement and materials of construction are essentially etermined by the pressure, temperature, speed of rotation and product being sealed (the slurry).
The Schurco expeller seal can operate completely leak free during pump operation.
The expeller rides along the shaft and expels material from the expeller ring cavity. Consideration must be given to inlet pressure and pump speed to ensure proper sealing with this type of seal arrangement. The typical installation introduces grease in lieu of seal water to provide a static seal against the inlet pressure when the pump is not operating.
