DSA and Monobore Systems
Pressure Pump
Flexibility of Two types, Skid Units or Trailer Mount Units
DSA (Dognut Sub Adapter)



Compact and Easily Accessible

Skid units are compact and moved with ease on PAD locations. All controls are user friendly and operated at ground level.

Fail Safe Over Pressure System

Equipped with a 15K pressure relief valve to prevent over pressuring, in addition a factory burst disc protects the pump from over pressuring.

Unique Hydraulic Operating System

Main hydraulic system is pre-set that controls the amount of flow to the pressure pump, which regulates the maximum desirable discharge pressure

Hydraulic Controls

Pumper is equipped with a high/low range which provides easy and gentle induction of fluids when pressure testing and starting ball displacement. Low range provides operator with more control and options

Secondary Hydraulic Source

Backup hydraulic system for operating the XL series and or remote valve systems

Manifold (annulus pressure system)

Annulus pressure can be maintained during ball launching operations.

Pressure Fluid Readings and Recordings

Full Electronic Recorder displays both lines pressure and rate with manual backup readings

Screened Buffalo and Coil Headers:
The slotted screen technology has proven to work extremely well in both the Buffalo Head (or Multi Port unit) and the Coil Headers. The results have been outstanding (refer to the IES Case Study report); we have quite the collection of debris, which includes multi sized rocks, pump parts and even a certification band that did not go down hole. This has our clients smiling and confident that unintentional pieces are not working their way down hole, which could seriously compromise downhole equipment and even create premature screen-outs. The results are much fewer screen-outs, downhole tools work more efficiently and reduces coil costs; all which positively reflect in your costs to complete the Wells. Our screens SAVE stages.
In addition the design allows for the fluids to disperse through a slotted area that in total triples the area (12.56 increasing to 36 sq inches) which results in managing erosion to perfection.

Trailer Mount Units
The IES Pressure Pump are Designed and engineered to displace packer balls into frac fluid pumped down hole. They can be utilized to maintain annulus pressure while displacing the packer balls during the pumping operation. In addition, they can be used to pressure test the fracheads when installed on location.
