Leistritz Advanced Technologies Corporation products

Leistritz L2 screw pumps are self-priming, positive displacement pumps that go to a pressure range of up to 250 psi. This is suitable for transporting fluids that are light abrasive, corrosive, high viscous, or low viscous. The fluid can have either poor or good lubricity.

A simplified three-rotor screw pump with total hydraulic balancing and built-in relief valve as standard features.

The two-rotor timed pump with external bearing allows pumping of practically any liquid.

This five-rotor single flow pump has a very high capacity paired with an extreme suction lift capability.

FLEXCORE is a flexible solution for installation in new and existing piping systems. It supports a broad range of applications including lubrication, fuel oil & burner services and hydraulic systems. Thanks to the unique modularity of the housing and the patented cartridge element, it is flexible for any installation position and standard. It is configurable for many different installation for flange orientations in 90° increments. FLEXCORE provides a higher flow rate at a smaller size. Extremely robust, virtually wear-free, and uniquely easy to maintain. It comes in steel and ductile iron options.

The Leistritz Multiphase Wellhead System (MWS) is a proven and economical method to assist artificial lift systems to accelerate production by lowering wellhead pressure and bottom-hole pressure to allow ESPs and plungers to operate above the bubble point for uninterrupted plateau production. MWSs handle total flow rates up to 100,000 bpde and differential pressures up to 500 psi. These fully automated systems have a small footprint and together with multiphase well testing will significantly reduce flaring, local separation facilities and stock tanks to allow operators to take advantage of more cost-effective centralized process facilities.

Typical gas wells produce not only natural gas but also liquids such as water and hydrocarbons like propane and butane. Except in wells where the gas is dominantly dry, condensate can build up down-hole, reducing the gas flow to an extent where the well is shut in and cannot buck the line pressure of the export flow line. The conventional method for mitigating this down-hole liquid restriction is to disconnect the well from the pipeline and then free flow the well into a portable tank until the gas begins to free flow again.

The Leistritz Multiphase Gathering System (MGSs) are expandable versions of the MWS, designed to handle production from multiple wells. Individual MGSs handle total flow rates up to 550,000 bpde and differential pressures up to 1400 psi. These systems are fully automated and can be expanded to operate multiple MGSs in parallel for facilities requiring additional flow capacity.

Oil wells assisted by ESP’s or sucker rod pumps tend to experience frequent or extended outages due to associated gas blocking the intake to plunger pumps and ESPs. If too much gas accumulates down-hole, the down-hole pump will simply shut down until enough gas passes up the annulus into the flow line and the liquid level is restored in the well. A typical method of assisting the gas flow through the annulus is to install a compressor. However, slugs of liquid tend to come up with the gas, which can overwhelm the compressor, resulting in damage, tripping their shutoff, and causing the down-hole pump to shut in production.

The PAMP, can stimulate your well’s plunger operations by removing the fluids above the plunger and reinjecting the gas through the annulus to increase run efficiency and decrease the down-time for pressure accumulation.
