5000 Series II Pump Unit

Product catalog summary

Overview
The document describes the features and specifications of the 5000 Series II Pump Unit, which is designed for hydraulic and electrical control in tunneling operations. It includes three independent hydraulic pump systems and a centralized operator station.

Features

High-pressure hydraulic system supplies oil for jacking cylinders at 5,100 psi and IJS cylinders at 6,000 psi, while a low-pressure system supplies oil to the TBM and conveyor at 3,000 psi.
Two independent hydraulic oil reservoirs: 160 gallons for the boring head and auxiliary systems, and 100 gallons for the jacking system.
High flow hydraulics (26 GPM) for quick jacking cylinder operations.
Simple operator controls for selecting hydraulic flow rates of 30/60/90/120 GPM.
Monitored input power for proper three-phase electrical power with a main disconnect switch.
Two independent water cooling systems with a single supply connection.
Standard and optional remote E-Stop buttons for safety.
Electric motors are fully enclosed and fan-cooled.
Low-pressure circuit powered by two 100 HP electric motors; high-pressure circuit powered by a 50 HP motor.
On-board oil fill pump for transferring oil through filters before entering the reservoir.
Vandal-resistant door for protecting operator controls.

Specifications

Hydraulic Supply: Three independent systems with individual oil coolers; cooling water required at 20-25 GPM.
Low Pressure: 2,800 psi with a maximum of 3,000 psi, powered by 100 HP motors.
High Pressure: 5,100 psi for jacking cylinders, powered by a 50 HP motor.
Dimensions: Height 90” (2,286 mm), Width 102” (2,591 mm), Depth 62” (1,575 mm).
Weight: 17,200 lbs. (7,802 kg) with oil.
Thrust: Total 400 tons (363 t) with two 200-ton cylinders.
Electrical Supply: 480V, 60 Hz, 3 Phase with a 100’ cable.

Additional Features

Load sense, variable volume, pressure-compensated pumps.
Water supply and discharge connections for cooling systems.
User-friendly controls for jacking cylinder, skid lock, and travel.
Filtered return oil with indicators to prevent improper servicing.
Electric motor controls and hourmeters for maintenance scheduling.
Individual pressure gauges for monitoring systems.
Phase Error indicator lights for monitoring electrical power.

The 5000 Series II Pump Unit is equipped with electric motor controls for ease of controlling the boring head, auxiliary and jacking system electric motors. Hourmeters for each system are also included to help determine maintenance intervals. All return oil is filtered prior to entering hydraulic reservoir (boring head/auxiliary return filters shown). The return filters are equipped with filter indicators to prevent under or over servicing of the filter elements. Easy-to-use operator controls for selecting boring head and auxiliary supply feed hydraulics (30/60/90/120 GPM). Main disconnect switch...
