Hand pump for filling solar systems

Product detailed description

The hand filling pump is used to fill and pressurise the solar circuit with heat-transfer fluid (antifreeze mixture) when commissioning the system or during servicing/topping up.

• volume of 3 dm3 / 3l 

• allows pressurising up to 4.0 bar

Frequently asked questions

• How do I check that this part fits my solar pipe/system? Compare the size/thread stated in this product's name with the diameter of your solar pipe or connection - solar components are usually manufactured in a few standard sizes (DN12, DN16, DN20, DN25).
• Why are solar components resistant to higher temperatures than standard heating parts? The heat-transfer fluid in a solar circuit can reach significantly higher temperatures than ordinary heating water under strong sunlight and low heat draw-off, so the seals, joints and components themselves are designed for higher temperature resistance.
• Does installation have to be carried out by a professional? We recommend leaving work on the solar circuit (especially connecting, sealing and filling the system) to a solar systems professional, since incorrect sealing or a leak can cause loss of heat-transfer fluid or air pockets in the system.
