5000 Series Pump Unit

Product catalog summary

Overview
This document provides technical specifications and features of the 5000 Pump Unit System, which is used in conjunction with Tunnel Boring Machines (TBM) for jacking operations. The system is designed to adapt to various jacking pipe lengths and diameters and includes two hydraulic systems powered by electric motors.

Features

The standard system includes the 5000 Pump Unit, skid base, and thrust yoke.
The pump unit advances the TBM and pipe along the skid base against the thrust yoke.
The skid serves as the foundation, transferring thrust to the reaction block.
The thrust yoke provides a 360° surface to minimize point loading on the pipe.
Hydraulics eliminate the need for high voltage electricity in the TBM.
The system includes a high-pressure system (8,000 psi) for jacking cylinders and a low-pressure system (2,800 psi) for the TBM and conveyor.
An optional auxiliary pump unit provides additional power to the low-pressure circuit.

Specifications

5000 Pump Unit Dimensions: Height: 90” (2,286 mm), Width: 93” (2,362 mm), Depth: 52” (1,321 mm).
Weight: With Oil: 12,600 lbs. (5,715 kg), Without Oil: 10,560 lbs. (4,790 kg).
Thrust: Total: 400 ton (363 t) with two 200 ton, 36” stroke cylinders.
Hydraulic Supply: A 5 HP electric motor provides 42 GPM for oil cooling and high-pressure charge supply systems. Cooling water is required for the heat exchanger.
Low Pressure: 2,800 psi with a 100 HP electric motor providing 60 GPM at no load or approx. 45 GPM at 2,200 psi. An auxiliary pump unit can double the flow to 120 GPM.
High Pressure: 8,000 psi with a 50 HP electric motor providing 9 GPM.
Electrical Supply: Standard: 480V, 60 Hz, 3 Phase; Optional: 415V, 50 Hz, 3 Phase.

5000 Pump Unit System with TBM 720

Skid Dimensions: Width: 80” - 91” (2,032 - 2,311 mm), Length: 30” - 270” (762 - 6,858 mm), Height: 25.5” (648 mm).
Skid Weight: Ranges from 1,500 lbs. (680 kg) to 12,600 lbs. (5,715 kg) depending on model.
Yoke Dimensions: Width: 72.75” - 93” (1,848 - 2,362 mm), Length: 93.5” - 123.75” (2,375 - 3,137 mm), Height: 51” - 93” (1,295 - 2,362 mm).

Auxiliary Pump Unit

Dimensions: H/W/D: 25.5x59x32” (648x1500x813 mm).
Weight: 1,500 lbs (680 kg).
A 100 HP electric motor provides power for 60 GPM at no load or approx. 45 GPM at 2,200 psi.

Additional Features

The dual ram & IJS control valve regulates the main jacking cylinders and the intermediate jacking station cylinders.
The 5000 Pump Unit is equipped with an E-Stop, operation lights, a low oil level indicator, and separate low and high-pressure system hourmeters.
The unit includes a 275 Gallon (1,041 L) Hydraulic Reservoir.
The pump unit is housed in a heavy-duty metal cab with locking folded doors to prevent vandalism.
Dual valves control the hydraulic oil flow to the boring head components.
