Circulation, glandless circulation pumps with increased lifetime. The idea of creating PUMPS OHI PRO was the conviction of necessity of construct a device with a more durable and more reliable construction compared to standard circulation pumps.

The pump uses a ceramic shaft with a higher density, and therefore also increased lifetime. The same applies to slide bearings. Strength of the motor and better electrical parameters were obtained through using winding in higher isolation class - F.

All production processes are carried out by robots. After each production stage, the robots also check the quality of the finished part. On the end each of pumps is electrically and hydraulically tested. Due to the elimination of the human factor from the production process, the final product is made in the highest quality, and the quality is repeatable in each copy.

All these solutions have allowed us to extend the warranty period to 3 years. The pump has 3 adjustable gears, depending on the needs installation. With pipe unions.
