Our Axial Flow Pumps are designed and built for reliable service, low maintenance and are backed by our long standing reputation for quality and attention to detail. Since 1936 Lawrence Series 9000  Axial Flow pumps have handled literally billions of gallons in many industries such as: chemical processing, refineries, power plants, petrochemicals, pump and paper, food processing,  municipal waste, and many other industries. Typical applications for the Axial Flow pump include evaporators, crystallizers, waste-water handling, sludge transfer, flood control, flume recirculation, irrigation, regeneration, heat recovery, and high-volume mixing.

Utilizing Lawrence's advanced propeller technology, special propeller designs are available, which can obtain in excess of 200 ft (61 m) TDH if required. Axial Flow pumps are designed for pressures and temperatures required to meet customers' specifications. LPI manufactures pumps in all castable materials including: Cast iron, Carbon steel, abrasion and corrosion-resistant alloys, stainless steels, Duplex alloys, Titanium, Zirconium, and specialtiy materials as required.

Design Features

All Horizontal Axial-Flow pump elbows are designed for uniform cross-sectional areas resulting in a normal velocity pattern. In critical reactor and crystallizer applications, the uniformly smooth flow allows better process control with minimal crystal degradation. This feature, combined with our low-shear propellers, improves process efficiency and output.

LPI's horizontal Axial-Flow pump is furnished with large-diameter shafts which are fully cantilevered into the elbow, completely eliminating the need for any internal support bearings. Large diameter shafts are designed for minimum deflection in the packing box area, allowing the use of either a mechanical seal or packed box design.

Small pump sizes use a combination of ball and/or roller bearings, while medium to large sizes use roller bearings exclusively. LPI utilizes thrust and radial bearings designs to provide a minimum L10 bearing life of 25,000 hours. For most applications, our L10 bearing life averages 50,000 hours. LPI's flexibility in bearing designs can provide L10 bearing life equal to 100,000 hours.

Lawrence Pumps Inc. invented the optional Back Pull-Out feature in 1956. This innovation simplifies internal inspection and maintenance of the rotating element and propeller without disturbing the suction and discharge piping or motor.  The reduction of downtime, and faster maintenance turnaround will mean significant cost savings.
