Leistritz offers 2,3,4 & 5 screw pumps with flows to 1200m3/h, pressures to 160 bars, temperatures to 320°C and viscosities to 200,000 cst. With a variety of screw materials Leistritz pumps can handle your toughest applications, ensure a very low noise level and almost pulsation free pumping action. Leistritz pumps are certified according to DIN EN ISO 9001:2000, DIN EN ISO 14001, GOST-R, GOSGOR TECHNAZOR, RS Supervisor and fulfil API 676. The casing of Leistritz pumps can be made by cast iron, Nodular cast iron, cast steel, aluminium alloy, bronze, stainless steel, cast iron or steel + Teflon graphite and the screw by hardened steel, high alloy, and stainless steel.
Leistritz Multiphase Pumps (MPP) are designed for both offshore and onshore oil production, for high-flowing wells, for marginal productions well, and to replace gas-lift systems. Leistritz pulsation-free screw pumps are ideal for multiphase production service because they can handle highly-viscous crude oil along with abrasive solids on a constant flow up to 330.000 GPD and differential pressures up to 1200 psi. They also work with very little inlet pressure (as low as abs. 0.2 bars), and are capable of handling high gas fractions (up to 100%), and are unaffected by slug flow. Unlike the conventional method, Leistritz MPP requires no separation of the oil, gas, water and solids produced by the well; no separate pipelines for transferring the oil and gas, and no compressor for moving the gas.
