Drum Pumps

Drum metering systems are available for both high and low-viscosity materials. Metering directly from a pail, drum, or tote dramatically reduces the waste and possible contamination of the product. The Mahr Drum metering pump is an accurate metering source providing continuous pulseless flow. Variable Frequency Drive control provides variable flow rates.

LV Drum Metering Pump – the LV series is designed for products that will flow freely as the unit is submerged into the product. This design is capable of metering viscosities up to about 90,000 cp. If your product will flow freely down the side of its storage source, the LV design will be suitable for your application. Generally, the drum metering pump is lifted via rigging overhead and the weights can vary from 7 to 45 Kg (15 lbs to over 100 lbs). Eye bolts are mounted to the drum pump according to the needs of the end user. A lift stand can be purchased by request of the customer.

HV Drum Metering Pump – the HV series drum pump is designed for thick viscosity, hard-to-pump products. The drum pump mounting is based on a platen design and follows the product from the top to the bottom of the drum as it empties. Pneumatics are utilized for both adding pressure to “ram” the product helping to feed thedrum metering systemand to lift the platen out of the empty barrel. Complete mounting of the pneumatics and pump.

Advantages of Mahr Drum Metering Pumps

Materials of Construction
Metering Pump

F16 – high tungsten, vanadium, and chromium alloyed high-speed steel. It is second only to tungsten carbide in wear resistance. This material offers excellent stability in high-temperature applications.

N19 – high chromium and molybdenum alloyed steel, similar to stainless steel, but it can be hardened. Excellent for processing very corrosive chemical substances.

DLC – coating can be used to harden and protect materials in extremely corrosive or abrasive applications.

All wetted mounting materials are stainless steel.
