Circulation Pumps

The WRAS-approved Watermill 2 Bar Twin Universal Brass Shower Pump is specialized for enhancing shower and basin tap water pressure within residential plumbing frameworks. It elevates the pressure levels, ensuring a fulfilling shower experience, especially with rain-type shower systems, pushing up to a peak of 2 bar pressure. This version of the pump is notable for its universal head, adaptable for configurations either both positive and negative head applications. Under positive head conditions, the water flow is automatically assured, with the source (like a cold water tank) positioned higher than the pump, ensuring gravity-fed water supply. But with negative, the pump pulls the water because …

The Grundfos STR2-2.0 CN 2 Bar Shower Pump, with its WRAS endorsement, is designed for integration within household plumbing. Its purpose is to amplify water pressure in showers or washbasin faucets, ensuring a more robust and enjoyable flow, especially in rain shower systems. It can achieve a peak pressure of 2 bar. This pump type is versatile, appropriate for scenarios with either a positive or negative head. In a positive head setting, the water flow is inherently direct. Typically, a cold water reservoir sits above the pump, allowing gravity to facilitate an uninterrupted flow to the pump. Conversely, a negative head implies that the pump doesn't get its water supply naturally since its …

The Grundfos STR2-1.5 C 1.5 Bar Shower Pump, with its WRAS endorsement, can be placed amidst the water channels in your residence to uplift water pressure when using showers or activating the washbasin faucet. This ensures an intensified water flow, with its peak pressure capacity being 1.5 bar. Designed with a positive head, this pump benefits from the spontaneous flow of water towards it. The water source, usually a cold water tank, is elevated at a distance of at least 1 metre above the pump. Due to gravity, water from the reservoir seamlessly courses into the pump. This arrangement makes it more efficient than pumps with a negative head, as it isn’t required to pull in water actively. Fu…

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 …

The Grundfos STN 3.0 Bar Shower Pump boasts WRAS approval. It is designed for home plumbing systems, effectively amplifying water pressure within shower units or basin faucets. This intensification in water flow is particularly satisfying for rainfall shower settings. It achieves up to 3 bar in maximum pressure. This pump works everywhere, for "positive" or "negative" water pressure situations. In positive setups, water moves naturally because the water tank is higher than the pump, thanks to gravity. Negative setups are different; the pump must work harder because the water doesn't flow into it easily. This is because the water tank is level with or below the pump. Here, the pump must actively …
