Saber NRG 18 ST3 Top Pump – 3 Stage Water Circulation & Agitator Pump for Beer Coolers

Saber NRG 18 ST3 Top Pump – 3 Stage Water Circulation & Agitator Pump for Beer Coolers

The Saber NRG 18 ST3 Top Pump is a 3 stage water circulation and agitator pump for remote beer coolers and draught dispense cooling systems. Designed to sit within the cooler water bath, it agitates the chilled water while providing circulation through compatible beer python cooling lines.

This type of beer cooler top pump is commonly used in pub, bar and brewery cellar installations where chilled water needs to be circulated between the remote cooler and dispense points.

The NRG 18 ST3 is designed for continuous operation and runs from a standard 220–240V, 50Hz supply.

3 Stage Top Pump for Remote Beer Coolers

A remote beer cooler uses a chilled water bath and ice bank to cool product passing through its coils.

The agitator section of the top pump keeps the water moving around the ice bank and product coils, while the circulation stages pump chilled water through compatible python pipework towards the bar and beer fonts.

This helps provide chilled water circulation around the draught dispense system rather than relying on static water within the cooler.

Beer Python Water Circulation

The 3 stage pump is designed to circulate chilled water from the remote cooler through compatible python cooling pipework.

In a typical installation, chilled water is pumped towards the dispense point before returning to the cooler as part of a continuous circulation circuit.

This is commonly used to provide cooling around beer python product lines and font trace cooling systems.

The actual circulation performance required will depend on the length, height and configuration of the individual installation.

Water Bath Agitation

As well as circulating water through the python, the pump incorporates an agitator for the cooler water bath.

Keeping the water moving around the ice bank and product coils helps distribute the chilled water throughout the cooler tank during operation.

Motor Construction

The NRG Series uses an extruded aluminium motor housing with Class F insulation and integrated thermal motor protection.

The motor shaft is manufactured from AISI 303 stainless steel, with NSK or SKF ball bearings used within the motor assembly.

The unit is designed for continuous operation in compatible beverage cooling applications.

Replacement Top Pump for Beer Coolers

The Saber NRG 18 ST3 can be used as a replacement top pump in compatible remote beer coolers where a 3 stage circulation pump and water bath agitator are required.

Before ordering as a replacement, check the existing cooler pump specification, mounting arrangement, electrical supply and water connections to confirm compatibility.

Important

This pump should only be installed in a compatible cooling system and in accordance with the manufacturer's instructions.

Always confirm the required pump stages, mounting dimensions, electrical specification and pipe connections before replacing an existing beer cooler top pump.
