XRP Horizontal Self Priming Multistage Pump For Seawater

XRP Horizontal Self Priming Multistage Pump The XRP is the self-priming version of the XM horizontal multistage pump. Either an electric or air vacuum priming pump is fitted to the body to enable full self-priming capability. This variation has the full ability of the standard version; however, it can only be used for clean liquids such as sea water and fresh water containing no solid particles. The XRP horizontal centrifugal multistage pump can be used for a vast range of applications in the industrial and marine markets. This range can achieve high pressures up to 55 bar and large flow rates of up to 1000m³/hr and is also very robust due to additional bearings being installed in the pump head, these remove strain away from the motor during operation. Common applications include boiler feed, chemical, energy plants, mining, firefighting, reverse osmosis, water treatment, pressurisation, dewatering, building systems, marine and cooling/heating conditioning (HVAC), petroleum, irrigation and water supply. This self-priming multistage pump is required when it is not possible to supply the inlet with fluid via gravity. This range is ideal for installations where the pump sits above the supply tank requiring a suction lift or where the inlet conditions are difficult such as long pipe runs. Priming is achieved by the main pump and the priming system working in tandem. They operate simultaneously, the priming device works by removing all the air from the inlet pipework, this draws the fluid into the body of the main pump, thus priming. A pressure switch then shuts down the priming device once the adequate pressure is achieved to enable to main pump to operate independently. The electric or air powered priming options are down to customer preference, however the air vacuum version is better suited for installations with long inlet pipe runs or where long priming times are anticipated as this option can dry run for small periods of time without damage. The horizontal centrifugal multistage design has many benefits: There are several options for flange configurations making it versatile when installing on sites with difficult pipework layouts. It is standardised to BB4. Multiple closed impellers and diffusers are installed to allow it to achieve very high pressures. This multistage pump has a maximum casing pressure of 63bar. It is fitted with sacrificial wear rings which are replaced periodically, this means the casing and impellers are protected from premature wear.
