The international requirements for the operational reliability of ships and machines in the shipbuilding and marine sector as well as the general conditions and limitations regarding energy efficiency and the emission of pollutants are constantly increasing. Leistritz has already been meeting these rising requirements for decades. High-quality products and the globally unique range of different types of screw pump designs offer the corresponding sustainability.
Robustness and production quality as well as long service lives and availability are the attributes which have always been associated with Leistritz screw pumps on the market. In order to be able to guarantee and document a consistent product quality, each Leistritz screw pump is thoroughly tested under the specified operating conditions on our test stands. During the course of the pump testing process, a factory 3.2 testing certificate in accordance with DIN EN 10204 can be delivered, as well as approval certificates as required for all notable ship class companies such as DNV, GL, ABS, BV, LRS, RINA and more.
L3N screw pumps
Leistritz screw pumps in the L3N range are three-spindle, single-volute, self-priming displacement pumps for the low-pressure range. They are used to transport non-abrasive lubricating fluids.
A wide variety of specialized vessels are generally used for the transportation of liquid freight on inland and shipping routes. In order to be able to safely load and unload the freight, these ships must be adapted for the specific storage and transport features. The same applies for the pumps which are used here. They have to ensure reliable and safe operation for a wide range of viscosities, temperatures and other operating conditions and influences. Here, Leistritz screw pumps offer optimal volume stability, robustness and operational reliability for almost all liquid freight goods and products.
L4 screw pumps
Leistritz screw pumps in the L4 range are twin-screw, double-volute, self-priming positive displacement pumps. They are used to pump aggressive / non-aggressive, abrasive / non-abrasive low to high-viscosity fluids with lubrication / non-lubrication properties. The spindles are manufactured in one piece which leads to low rotor deflection and non-contacting design. The special spindle geometry minimizes pulsation and optimizes the NPSH value.
The arrow-toothed gears helps to reduced the noise level. The advantages of the replaceable insert is easy to see in the low-maintenance.
