D-A Lubricant’s BioBlend PPL is a readily biodegradable lubricant for the plunger packing in positive displacement reciprocating pumps, such as triplex and quintuplex pumps used in oil and gas hydraulic fracturing and cementing operations. It is formulated from renewable biobased resources and contains no mineral oil or toxic additives, thus reducing environmental impact associated with the handling and use of lubricants in these operations. Additionally, the blend of highly refined natural ester base oil and bio-based polymer in BioBlend PPL reduces friction compared to conventional mineral oil-based lubricants, which translates to less wear and extended packing life.
