The Benchmark in LPG

Blackmer offers a full line of LPG pumps and gas compressors, designed for maximum performance and reliability. LPG is an abbreviation for "liquefied petroleum gas" and encompasses several other hydrocarbon gases like propane and butane. These LPG operations can often cause excess rigors on equipment, as cavitation in less lubricated propane applications is a common issue. All Blackmer propane pumps feature a cavitation suppression liner that helps minimize the damaging effects of cavitation in LPG applications. Our full line of stationary propane pumps and gas compressors help LPG operators efficiently load and unload their transport means, speed up product transfer, complete tank evacuation and improve vapor recovery to meet regulatory and business profitability objectives. 

5-Year Product Warranty & 2-Year Performance Assurance

Blackmer stands behind the quality of our LGL Series Sliding Vane Pumps (LGL, TLGL and LG models), LB Series Gas Compressors and our BV model bypass valves with an unmatched extended five-year Product Warranty* and two-year Performance Assurance Guarantee*. The extended Product Warranty and Performance Assurance programs are evidence of the reliability and confidence customers can place in Blackmer LGL Series propane pumps, the industry’s leading sliding vane propane transfer pumps, and our LB Series propane gas compressors and BV bypass valves.
