Hydraulic power supply

The hydraulic power is supplied to the laboratory through a 40 gpm MTS 506.41E and a 180 gpm Shore Western (SW) WhisperPak 1180. These two pumps are capable of functioning separately (a 40 gpm or a 180 gpm flow rate) or simultaneously (220 gpm flow rate). Furthermore, SW WhisperPak 1180 has an on-demand feature which can reduce the flow to 120 or 60 gpm automatically through an embedded control system during operation. The total reservoir capacity between the two pumps is 725 gallons.

A 100 ft long stainless steel hardline is embedded inside a trench that spans a large portion of the Laboratory as shown in the lab layout. The hardline system consists of a 2 ½ inch schedule 160 304SS pressure line, a 2 ½ inch schedule 40 304SS return line and a 1 inch schedule 40 drain line. Ten take-off points are installed along the hardline and the hardline system is rated for a maximum flow rate of 220 gpm. Additionally, to maximize the performance of the distribution system accumulators are installed at each terminal location, one with a capacity of 30 gallon for the pressure line and 10 gallon for the return line, and the other with 45 gallon for the pressure line and 10 gallon for the return line.
