KRAL AG has launched its Series Z, a new line of two screw pumps which are specifically designed for use in the tank farms and tank terminals of the oil and gas industry.
In this market, screw pumps are becoming increasingly popular because their flow rate can easily be controlled by the engine speed and pumping media with different viscosities and high gas fractions can be conveyed. They are capable of delivering contaminated, aggressive and low- or non-lubricating media. These technical advantages reduce operating costs and make screw pumps attractive for the oil and gas industry.
These new KRAL screw pumps feature an unlimited variability to arrange inlet / outlet connections and thus offer maximum flexibility for connections. Existing systems often have limited options for arranging the pump. Using the KRAL Z series, the user can freely choose how to arrange both suction and pressure flanges. All the connections can be arranged either for horizontal or vertical installation inline at several angles.
The innovative delta shape of the pump housing allows a good suction performance and dry running properties, even with a gas content of up to 80%. The housing is standardised, which simplifies warehousing and speeds up spare parts delivery.
Multi-part rotors can be braced with little effort and without loss of quality on site which reduces the downtime of the systems and saves costs. Due to the type of bracing, the rotor can be loaded higher.
The pumps also offer adjustable screw design. This enables the pumps to be used in a very broad range of applications. The KRAL Z series can be designed with one-piece or multi-piece screws. Thanks to parts reduction, one-piece screws offer considerable cost benefits, whereas multi-piece screws have the advantage that combinations of different metals can be used. For example, a combination of steel and bronze can be used to convey salt water.
