China Serva Auto Density Control Double Pump Cementing Skid Made in 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
PCS-821B Auto density control double pump cementing skid is newly developed cementing equipment based on QPA1000 plunger pump and ACM-IV.1 auto mixing system.
QPA1000 pump is applicable for deep well cementing, sand control equipments, small and medium-sized fracturing jobs. With features of light weight and compact structure, it is the new model with power between 600HP and 1800HP which fills up the gap with no suitable cementing plunger pump. Many components of QPA1000 and TPB/TPD600 pump can be used interchangeably. The high energy mixing system of the skid is mainly driven by two transmissions PTO. The entire skid is compact, applicable for the areas with strict requirements for space, such as offshore drilling platform, etc.
