China Double Pump Cementing Skid From Serva China

Skid mounted cementing equipment is mainly utilized in offshore or remote areas on land, such as desert where the vehicles are difficult to reach. Three kinds of major cementing plunger pumps of TPA400, TPH400 or TPB600 and variety of plunger size can be selected according to different operating conditions. The unit is fully considered the anticorrosion for offshore application. Zone-II explosion-proof unit is also developed, for the characteris­tics of offshore platform
I.Overview
Model PCS-421B is an integral skid mounted mixing and pumping unit which is state-of-the-art in continuous mixing and density automatic control.
It mainly consists of skid frame, two engines, two transmissions, two TPA400 triplex pumps, hydraulic system, nigh and low pressure system and ACM auto mixing system. The High energy mixing system is powered from two transmissions PTO. The entire skid is very compact and applicable for offshore drilling platform.
This unit is mainly utilized in cementing job, acidizing job, oil well pressure testing, and other fluid pumping job in offshore, on land or desert oil field.
