Use of Marshalsea Pumps with Castrol TransaquaWater Based Subsea Control Fluids

Castrol Offshore has worked closely with Marshalsea Hydraulics to ensure thatMarshalsea’s range of Water Glycol Pumps are fully compatible with Castrol’sTransaqua range of products.

Castrol has an extensive track record with Transaqua fluids in these types of highpressure Water Glycol Pumps. The Marshalsea design of pump provides a separatebearing oil lubrication system that separates the pumped product from the bearingoil. This provides a robust design, which gives long and reliable operation withCastrol water based control fluids. We recommend Castrol Alphasyn PG gear oils foruse in the bearing lubrication system; these oils are fully compatible with theTransaqua range of control fluids.

Marshalsea pumps which incorporate separation of the lubricating oil and thepumped fluid are approved for use with the following Castrol Transaqua grades.

Overview

Water & Oil Based Fluids Pump / Motor Pump Unit Type XWH

MAJOR PROJECT SUCCESS




The high pressure 50 kW (350 kg) Type XWH Hydraulic Pump is specifi cally designed for water-based fl uids. Separation of the lubricating oil and the pumped fl uid is achieved by the installation of a cavity between the cylinder block and the case. Bypass from the pistons is collected in this cavity and returned to the inlet side of the pump. The XWH pump incorporates six axial pistons actuated by a single rotating swash plate.This high powered pump is highly suitable for Blow Out Preventer (BOP) applications, hydraulic power units (HPUs) and fl ushing skids.

All external pump components are manufactured from 316 Stainless Steel.

Rotation is bi-directional and the pump is mounted horizontally. A suction fi lter of at least 60 microns should be used,and care should be taken to ensure that the fi lter is of adequate size and does not cause more than 300mm Hgdepression. Pipes/tubing should be of suffi cient size to give not more than 3.7m/sec velocity in the delivery line and1.2m/sec in the suction line. The suction line should be kept under positive pressure when the pump is stationary toallow priming.

The pump model XWH is compliant to API 674.

Certifi cation Details

This pump conforms to European Directive 94/9/EC relating to equipment intended for use in potentially explosive atmospheres and is ATEX compliant.

Bifold Marshalsea has been third party assessed and certifi ed as meeting the requirements ofISO 9001: 2000 for the design, development, manufacture and servicing of Hydraulic Pumps,Relief Valves and Pressure Intensifi ers.

Pump Comparisons

Comparison of Pump Types




Comparison of Pump Types forWater-Based Fluids

Figure 11 shows the internal arrangement of a typical three piston triplex pump design. As can be seen from previous illustrations, pumps of this design are large and occupy asignifi cant level of skid space. An external drive belt and pulley system is needed to drive these pumps. Typically, motors are mounted on top of the pump producing a large unit.Guarding is required to enclose the belts further adding to the overall footprint and cost. Anti-sparking materials and corrosion protection are necessary for the external drive system components and guards. It is unusual for pumps of this type to be manufactured from stainless steel and as such further corrosion protection required.

Pulsation dampers are generally required when usingtriplex pumps.

The Bifold Marshalsea compact pump design is shown in fi gure 12. The motor is close-coupled to the pump, negating the requirement for pulleys and drive belts. There are no exposed rotating parts resulting in improved user and application safety, particularly in hazardous (classifi ed) locations.These pumps are manufactured from 316 Stainless Steel. The fl ow delivery of these pumps is smoother than with triplex pumps and there is generally no requirement for pulsation dampers. Since the design does not have belts or pulleys and is dynamically balanced, it has extremely low levels of vibration.
