Product Description

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-621B Auto density control double pump cementing skid is new generation of cementing unit with adoption of plunger pump TPB600 and ACM-lll.1 auto mixing system.
SERVA TPB600 pump has prominent features of small ersize and lighter weight. With two pump back to back installation, the overall width will only be 2580mm which can extremely decrease the overall dimension (weight) of unit, especially applicable to truck- mounted units or offshore equipments.
The high energy mixing system is mainly powered by two transmissions PTOs. The entire skid is very compact, so it is applicable for the areas with strict requirements for space, such as offshore drilling platform, etc.
