The most widespread problem of viscous oil production is leakages which appear as valves cannot be closed on time. As the solution of this problem our specialists developed specialized sucker rod pump SPeaR. It has the nominal size from 1 3/4″ to 2 3/4″, plunger stroke length up to 6000 mm (19,7 ft), mechanical sealing with eccentric rings and positive opening plate-type standing valve. Besides SPeaR pump is operated together with flexible cable rod for oil production from deviated wells.
SPeaR differential pump is used for production of highly viscous oil and emulsions, prevents floatation of sucker rod string and improves pump efficiency.
