Termed the screw pump for demanding liquids, the new twin screw designed Z Series from Kral is suitable for even aggressive and contaminated media.

Applying their years of experience and expertise, KRAL have designed a new two screw pump that is highly versatile and possibly the only thing like it on the market.

The Z Series is capable of extreme pumped media temperatures, from as low as -40°C up to +150°C. Delivering aggressive, low- or non-lubricating and contaminated media with reliability. The inlet and outlet connections can be arranged in almost any direction on both horizontal and vertical installations.

The Kral Z Series is designed to be a customised solution for any required application. The screws can be designed solid or engineered with results benefitting fatigue strength, media resistance and maintenance costs at a substantial level. For example, a combination of steel and bronze can be used to convey salt water.
