Authorized Distributor of Metering Pumps

For precise and robust metering pumps, Coker Pump & Equipment Company remains a trusted leader for our Nevada and Central Valley / Bay Area customers in California. Our pumps, available from many top manufacturers, handle a variety of flows and pressures. For example, we carry the Neptune 500 Series of Metering Pumps. This line features the Variable Oil By-pass™ stroke adjustment feature which allows for better valve performance than variable linkage designs. We also offer the sturdy DMH Hydraulic Diaphragm Metering Pump line from Grundfos. Its many features include maximum pressure up to 2900 PSI, with a duplex option for doubled capacity and double diaphragm leak detection. And Hydra-Cell metering products are compact, cost-effective pump systems with high performance ratings, including precise accuracy of +/- 1% and repeatability to 3% or better.
