XHL Long Coupled Centrifugal Pump

XHL Long Coupled Centrifugal Pump Flow RateUp to 1500m³/hrHead (Pressure)Up to 100mInlet/Outlet SizesDN32 to DN250Operating Temperature-10°C to +140°CDrive OptionsElectric Motor, Engine The XHL long coupled, end suction, single stage horizontal centrifugal pump is standardised to EN 733 / DIN 24255 and can be used for a vast range of applications in the industrial and marine markets. It is designed to pump low viscosity clean or slightly contaminated fluids without the presence of solid or fibrous particles. Common fluids pumped include fresh water, sea water and fuels (diesel, petrol and kerosene) and common applications include fuel transfer, chemical, energy plants, mining, fire fighting, irrigation, water supply, water treatment, pressurisation, grey water, dewatering, building systems, marine and cooling/heating conditioning (HVAC). This is a large heavy duty horizontal centrifugal pump with high flow and high pressure capabilities. The long coupled horizontal centrifugal pump configuration has many benefits: The long coupled design is very easy to maintain as it is possible to access the pump head without removing the motor. This centrifugal pump is also more robust and designed for continuous use as additional bearings are installed in the pump head, these take a large deal of strain away from the motor during operation.The back pull out design allows the motor to be removed while the pump is still connected to the pipework, this in turn allows time saving while the pump is serviced/maintained. The centrifugal pump and motor have independent shafts, this means that only the pump shaft will need to be replaced in the event of it breaking. Other less robust horizontal centrifugal pumps on the market only use the motor shaft, this means that if the shaft breaks, the entire motor needs to be replaced. The long coupled design means that there is a large space between the pump and motor, this in turn protects the motor from fluid ingress in the case of a seal failure. Wear rings can be installed in the pump head, this is a sacrificial part that wears first protecting the impeller and casing from wear and prolonging the life of these parts and therefore the pump. The long coupled horizontal centrifugal pump complies with DIN 24255 and EN733, this means that the pump is dimensionally the same as many other pumps on the market, this enables the replacement of most horizontal centrifugal pumps that are already installed. The XHL long coupled horizontal centrifugal pump is also available in an ATEX version for handling flammable fluids or being installed in a non-safe area. If required, the XHL horizontal long coupled centrifugal pump can be supplied with an external air powered or electric priming pump for applications where a suction lift is unavoidable.
