Grundfos STP-3.0 B

The Grundfos STP 3.0 Bar Shower Pump, certified by WRAS, can be positioned between your house's water pipes to augment water pressure during showers or when you open the washbasin faucet. It amplifies the water flow, allowing for a more robust flow. Its maximum pressure capability is 3 bar.

This pump operates with a positive head, indicating the water's natural flow towards it. The originating water source, typically a cold water reservoir, is positioned at least 1 metre higher than the pump. The gravitational pull from the reservoir ensures the water flows effortlessly into the pump. This design means it works more efficiently than a pump with a negative head, as it doesn't need to actively draw in water. Moreover, this setup reduces the chances of air accumulation, which hinders the pump's optimal performance.

Constructed of brass and stainless steel, the pump is ideal for transporting tap water because it averts the dispersion of rust particles in the water. This pump design includes dual impellers, allowing it to handle both hot and cold water simultaneously. This ensures a steady water flow, even if someone is using another tap simultaneously. The pump also incorporates anti-vibration and non-slip feet, ensuring its quiet operation.

It's essential to note that directly connecting this pump to the main water system is illegal in the UK. Such a connection might impact the broader water supply, reducing water pressure for neighbouring properties.

Understanding the Grundfos STP 3.0 Shower Pump's Operation:

The Grundfos STP 3.0 Shower Pump automatically activates or deactivates based on water flow. Once a faucet is opened, the water's movement triggers the pump, and it deactivates when the flow ceases upon closing the tap.

Water from the primary pipeline enters the cold water reservoir, which has dual exits. One directs water to the hot water tank for heating before reaching the pump. Concurrently, the other allows cold water to flow straight to the pump. The pump then amplifies the water pressure, dispensing it with increased pressure to the designated outlets.
