Hand pump for filling installations 73.02.00

Professional tool for filling heating and solar installations

The HEWALEX hand pump is a specialized device designed for the professional filling of heating and solar installations with a heat transfer medium. Thanks to its simple piston design and solid technical parameters, it provides a reliable solution for both professional installers and end users performing service work.

Construction and principle of operation

The device utilizes a proven piston pump design with a tank capacity of 3 dm³, ensuring an adequate amount of fluid for a single filling of smaller installation sections. The principle of operation is based on generating air overpressure above the liquid surface in the tank - this simple mechanism enables effective injection of the fluid into the heating or solar circuit without the need for complex electrical devices.

The set includes all necessary elements: solar pump tank with hose, solar pump piston rod, and a funnel to facilitate tank filling. The 1,4 m long hose with a standard ¾" connection provides adequate flexibility when working in various installation conditions.

Operating parameters and application possibilities

The pump enables the generation of overpressure in the installation up to 3 bar, which is a sufficient value for most standard domestic heating and solar systems as well as small-scale commercial applications. This pressure range allows for effective venting of the circuit and injection of the heat transfer medium even under higher hydraulic resistance.

The 3 liter working capacity allows for efficient fluid replenishment in systems of various sizes - from single underfloor heating loops to larger solar installations requiring periodic heat transfer medium replenishment.

Practical application and user benefits

During the initial commissioning of new installations, it is necessary to fully fill them with a heating medium. There is also a need to replenish fluid during service and maintenance work following fluid loss or the replacement of circuit components.

The lack of electrical power allows for operation in field conditions without access to the power grid. The simple operation can be quickly mastered thanks to the intuitive piston mechanism.

The standard ¾" threading ensures compatibility with most hydraulic accessories available on the market.
