KRAL Screw Pumps Z Series
In the new Z series, KRAL applies its expertise in pump de-
sign and technology to two screw pumps. As a result, the
KRAL Z series is capable of delivering aggressive, low- or
non-lubricating, and contaminated media with the reliability
and quality that KRAL products are valued for by customers
worldwide. In keeping with its commitment to constant innovation, KRAL has integrated an important new feature. The
ability to arrange the inlet / outlet connections in any desired way (see page 10-11). This is a new feature for pumps of this
type, and there is nothing like it on the market.
The KRAL Z series features synchronized, two-spindle screw
pumps with a double-suction design. Because the screws are
synchronized and hence contact-free, they can deliver even
contaminated and non-lubricating media reliably and without
pulsation. Dry running is possible, too. The double-fluted design facilitates very high delivery rates and axial pressure
equalization in the pump housing, which ensures that the
pump has a long lifetime.
