The ECO SNL-SP is the self-priming version of the ECO SNL vertical inline centrifugal 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 ECO SNL-SP single stage vertical centrifugal pump can be used for a vast range of applications in the industrial and marine markets. Common applications include irrigation, water supply, water treatment, pressurisation, grey water, dewatering, building systems, marine and cooling/heating conditioning (HVAC).
This self-priming centrifugal 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 vertical centrifugal pump configuration has many benefits:
The compact vertical centrifugal configuration means the pump can be installed where there are space limitations. 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 vertical centrifugal pumps on the market only use the motor shaft, this means that if the shaft breaks, the entire motor needs to be replaced.
A lantern bracket is installed between the pump and motor, this creates a space protecting 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.
