The World's Only Open-Frame Submersible Plunger Pump for Depths of 10,000 feet

Without a doubt, Jetech's XP-UW 100J3 Subsea Ultra-High Pressure triplex pumps represent a new era in underwater pumping equipment. Engineered to function in sub-sea environments, the pumps are capable of operating up to 40,000-psi (2750 bar) dis­charge pressure. The XP-UW 100J3 pumps “DO NOT REQUIRE OIL OR GREASE” in the power-end. They are engineered to operate using seawater for cooling and lubricating the bearings and other moving components.

Jetech’s specialty line of industrial submersible pumps can be manufactured in sizes up to 700 horsepower.  The high-pressure submersible pumps have a proven track record of dives and are designed to operate in underwater depths of 10,000 plus feet.

When mounted onto an ROV, thousands of dollars of expensive ultra-high pressure hose is eliminated. Depending on the operating depth, savings can ex­ceed $100,000 dollars. In addition, only about 20 feet of hose is required and excessive pressure drop associated with long lengths of the hose is elimi­nated. This permits all pressure generated by the submersible pump to do productive work which means increased efficiency in the water jetting process.

The unique design of the submersible pumps permits the crankcase of the pumps to be flooded by seawater and thus, have zero differential pressure between the internal and external casing of the power-end. This will allow the underwater pumps to operate in the deepest depths of the ocean.

The XP-UW Subsea pumps are well suited to be driven by a direct connected hydraulic motor and are available with a right or left-hand drive shaft.

The pumps are made with all stainless steel construction including the power end. This permits corrosion tolerance to seawater.

The main and connecting rod bearings are designed and manufactured by Jetech and are non-metallic, IOS-3000 material.

All the tie bolts are stainless steel or nickel coated to help prevent rusting and corrosion.

Applications: 

  • Hydrostatic testing, 
  • Blow out preventer (BOP) testing
  • Methanol injection
  • Pipeline lining/coating removal
