WORKING BALLS PVAF-68, PVAF-77 AND PVAF-94mm.
When it comes to pumping water from your own sources, having reliable and efficient technology is key. One of the latest and proven solutions are the PVAF-68, PVAF-77 and PVAF-94 working cylinders, which represent an innovative approach to improving the performance of Floris wind and hand pumps. After several years of testing, these cylinders have proven to be unmatched in reliability and efficiency, making them ideal for a wide range of applications.
Design innovation and easy maintenance
The PVAF working cylinders are made of PN16 PVC-U pressure pipe with a length of 330 mm, which ensures their high durability and long service life. They are fitted with glued-on adapters at both ends with 2 1/2″ female threads, allowing for easy assembly and disassembly. This design allows for easy replacement or repair of the piston from above, without the need for complex disassembly of the entire system.
Higher efficiency and less wear
The pistons in PVAF cylinders are specially designed to eliminate water leakage when moving slowly upwards, greatly increasing their efficiency. In practice, this means that the risk of rapid wear of the sleeves and the cylinder itself is reduced, leading to long-term reliable operation without the need for frequent repairs.
Durability and wide range of applications
Due to their design, PVAF cylinders are ideal not only for normal drinking water pumping, but also for water with a high iron content or salt water. One of the main advantages of these cylinders is the fact that they do not rust, which ensures their long-term durability even under harsh conditions.
High efficiency and minimal maintenance
Long-term tests have shown that PVAF working cylinders achieve efficiencies of up to 94%. The need for replacement sleeves is also minimal, which significantly reduces operating costs. In addition, thanks to the use of quality materials with drinking water certification, there is no need to replace the cylinders throughout the lifetime of the pump.
Cost-effective
In addition to the technical advantages, PVAF impellers also offer an economic advantage. Thanks to their long service life and minimal maintenance requirements, their price is very favourable compared to other solutions available on the market.
