* * GSH HVAC OEM * CIL2 Series pump introduce Reliable and noiseless Grundfos UP pumps A Grundfos UP pump is a wet runner with an asynchronous motor. The entire shaft, including rotor and impeller, is running in the medium (e.g. water). Consequently, the pump is without a shaft seal that has to be maintained. Instead, a stainless steel rotor can, stretched as one part, separates the stator and the rotor and prevents leakage. The shaft, the two radial bearings and one part of the axial bearing are made of tungsten ceramics – normally the hardest material inside a heating system. And if there is water inside the pump, the hydrodynamic principle causes the shaft to swim upon a thin water film, much like aquaplaning. Advantages of the construction ? No maintenance – low costs ? No leakage – high reliability ? No noise – high comfort ? No wear – long life The new LOW ENERGY OEM circulator range UPSO ? Different motors combined with different housings ? Free choice of terminal box position, name plate position and power supply plugs (or cables) ? Variable by using up to 3 speeds ? Anti-blocking laser hole shaft ? Long life tungsten shaft and bearings ? Environmentally friendly without antimony, lead, etc. ? Composite housings--Comply with the requirements of the United Kingdom Water supply (water Fittings) Regulations/Scottish Water Byelaws. ? IP 44, CE-Approval LOW ENERGY Grundfos “Low Energy” pumps are designed to reduce the energy consumption of the pump by up to 35 % depending on the pump type. They are available as standard pumps with 1 to 3 speeds as UPO, UPSO. To further reduce the power consumption – especially in a low load situation – electronic controlled pumps are available as Low Energy Grundfos UPER or as Grundfos UPM in permanent magnetic technology. Application CIL2 Series pump application CIL2 series pump is to be used in a heat pump and gas-boiler combi systems. Primarily circulation of liquid in : . Central heating system . District hea
