SmithLift has developed and field proven the Hydraulic Diaphragm Electric Submersible Pump (HDESP). The pump is powered by a three phase, triple insulated electric motor and uses two hose-like "diaphragms" to positively displace formation fluid into the production tubing. The pump was designed for low-production-rate (<200 bfpd) oil, gas and coal bed methane applications with depths less than 2,500 ft.
