Vindum Engineering, Inc. specializes in manufacture of high-pressure, high-precision, pumps and valves for laboratory and pilot-plant applications. Founded in 1987, VEI has worked continuously to advance the design of high-pressure metering pumps. The Vindum Constant Volume Valve (CV Valve) is a patented design developed in tandem with the first pulse-free, continuous-flow, dual-piston, metering pump. Today, the Vindum CV Valve remains a staple of high-pressure lab work, due to its durability, rapid actuation, and adaptability to a wide range of applications and operating conditions. VEI entered a new chapter in 2015, with the release of its VP-Series metering pumps. Designed and built in-house, the VP-Series pumps are the most advanced dual-piston, continuous-flow, laboratory pumps available today. Industry and University response to the VP-Series pumps has been very good, with a growing list of satisfied customers in countries across the globe. Our newest model is the VP-25k, the only dual -piston pump verified to deliver fluids pulse-free and continuously at 25,000 psi. In 2016, VEI introduced a line of Hastelloy needle valves rated for 12,000 psi service. These small valves, designed for use with corrosive fluids, use the same O-ring seal design that has proven so durable in the Vindum CV valves. The MV valves and fittings continue VEI’s history of developing innovative high-pressure flow-control products that offer excellent performance and value. VEI also sells oil & gas laboratory test equipment made by selective manufacturers, including DMT (Germany), and NER (USA).
