Polyolefin Reactor Pumps

Polyolefin Reactor Pumps

Axial Flow Circulators
for Polyolefins Loop Reactors

LPI has been manufacturing Axial Flow Pumps for more than 50 years and Propeller Pumps for Polyolefins Production for more than 25 years. Today LPI is recognized worldwide as both a high quality manufacturer and a technological innovator of Axial Flow Propeller Pumps for Polyolefins production. Since the mid 1970's, when LPI developed its first loop reactor pump design, LPI's Axial Flow Pump technology has evolved significantly.

To respond to the challenges of advanced and evolving Polyolefins processing, LPI continues to engineer and manufacture a wide range of high performance custom pumps. Innovative, industry-proven technologies and numerous design options ensure that every LPI Axial Flow Pump meets and/or exceeds each customer's performance criteria for reliability, efficiency and environmental safety.

Testing and Advancement

LPI maintains a fully equipped, simulated test loop with a full scale 24" Reactor Circulator Propeller Pump. This test loop is dedicated to developing advanced hydraulic and mechanical capabilities to meet our customers' advanced process needs and to help them achieve the highest throughput, productivity, and reliability possible.
