Grundfos - UPS 15-50N Domestic Hot Water Service Pump Circulator - 230V - Stainless Steel
UPS 15-50 N 130
The pump unit is of the canned rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricatd by the pumped liquid. The pump has 3-step speed selector. The pump is characterized by:

Stainless Steel pump housing
corrosion-protected impeller, Composite
Stainless Steel rotor can and bearing plate
Carbon axial bearing
Ceramic shaft and radial bearings

The motor is a 1-phase motor. No additional motor protection is required.

Suitable for: Commercial heating, Domestic heating, Domestic hot water recirculation

Grundfos - Spare/Slave Home Booster Water Tank - 180Ltr

The Grundfos Home Booster is a self-contained cold-water Booster Set is specifically developed to be used in properties or buildings where the existing mains water supply is insufficient to meet the standard pressurised hot and cold-water system demands.
For a slightly higher demand, or where the storage tank refills very slowly due to poor mains water pressure.
This product is the 180 litre extra storage tank for the home booster unit.
The Grundfos Home Booster sets can be used in conjunction with a 180L Slave Tank for applications requiring additional water supply.
The Slave Tank is compatible with the 3.0 Bar.

Grundfos (est. 1945) is a Danish pump manufacturer known for high-efficiency circulators, multistage boosters, borehole and wastewater pumps, plus packaged pressure systems. The range covers HVAC circulation, domestic hot water recirculation, pressure boosting, industrial water transfer and public water management, with strong focus on energy efficiency and intelligent controls.
