Last year Hidrostal launched the A2U Compact Pump, redefining standards for reliability, flexibility, and efficiency in high demand pumping applications. While many pumps claim clog-free capabilities, Hidrostal has taken it a step further—proving it. Through in-house testing, the A2U Compact Pump has demonstrated its ability to handle large solids without blockage, showcasing a level of performance that goes beyond promises to practical, verified results.
In the test, a Hidrostal A2U-E1G-52B pump was mounted on an H0-TA02/K/R base plate and used to circulate golf balls through the pump’s circuit. The video documentation shows each golf ball passing seamlessly through the pump without causing any blockage, even when operating at varying frequencies from 20 to 50 Hertz.
This impressive test confirms the A2U Compact Pump’s unique clog-free design and highlights its efficiency in handling large solids.
The A2U Compact Pump features Hidrostal’s unique screw centrifugal impeller and a 50 mm free ball passage for clog-free operation. Lightweight it’s easily transportable yet powerful, with a range of 0.5 to 1.6 kW. Built from durable grey cast iron, it delivers up to 10 l/s with a 10 m head, operating continuously in both dry and submerged setups. Its modular design supports custom configurations for various speeds, voltages, and materials, while flexible connections—including thread, flange, and Storz coupling—allow for both vertical and horizontal installation.
The A2U series is certified for Ex zones 1 and 2 under IECEx and ATEX, confirming its suitability for high-demand environments. Equipped with dual mechanical seals and premium elastomers, it’s built to last, delivering dependable, low-maintenance performance across industries. The A2U Compact Pump demonstrates Hidrostal’s commitment to innovative, clog-free solutions that meet diverse industrial needs.
