Adhesive and sealant production presents unique pumping challenges because these materials are often highly viscous, shear-sensitive, and prone to buildup inside pumping equipment. Products including polyurethane adhesives, silicone sealants, acrylic adhesives, epoxy resins, latex, hot melt adhesives, and pressure-sensitive adhesives require pumping systems capable of maintaining stable flow without introducing excessive shear or contamination.

Traditional gear pumps, progressive cavity pumps, and centrifugal pumps often experience product buildup, difficult cleaning procedures, mechanical seal failures, and increased maintenance costs when handling sticky materials. Product hardening inside pump chambers can reduce efficiency, increase downtime, and shorten equipment life.

Air Operated Double Diaphragm (AODD) pumps have become one of the preferred technologies for adhesive manufacturing because their seal-less construction minimizes leakage while their reciprocating pumping action provides gentle handling of shear-sensitive materials. Self-priming capability, dry-run operation, and the ability to transfer highly viscous fluids make diaphragm pumps particularly suitable for demanding adhesive applications.

OVELL AODD pumps are engineered specifically for industrial adhesive and sealant manufacturing. Featuring robust construction, excellent chemical compatibility, and advanced Integral Piston Diaphragm (IPD) technology, OVELL pumps significantly reduce internal product buildup while extending diaphragm life and lowering maintenance requirements.

Whether transferring silicone sealants, polyurethane adhesives, hot melt compounds, latex emulsions, epoxy resins, or construction adhesives, OVELL diaphragm pumps deliver consistent flow, excellent product containment, reduced downtime, and reliable long-term performance across modern manufacturing facilities.

OVELL Air Operated Double Diaphragm (AODD) Pumps are trusted worldwide for transferring high-viscosity adhesives, sealants, latex, epoxy, polyurethane, silicone, and other demanding industrial fluids. Their seal-less design eliminates common mechanical seal failures while providing leak-free product containment and superior operational safety.

Compared with conventional pumping technologies, OVELL diaphragm pumps offer exceptional self-priming performance, dry-run capability, excellent suction lift, and gentle low-shear fluid handling. These advantages help manufacturers reduce product waste, extend equipment life, minimize cleaning time, and improve overall production efficiency.

The patented Integral Piston Diaphragm (IPD) technology further minimizes adhesive buildup around the piston, reducing maintenance frequency and extending diaphragm service life. As a result, OVELL AODD pumps have become an ideal solution for packaging, woodworking, automotive, construction, chemical, and industrial adhesive manufacturing applications where reliability, cleanliness, and consistent production are essential.
