ENGINEERED FOR MAXIMUM EFFICIENCY AND CONTINUOUS DUTY.
Boltorq pump systems are built with specialized components to ensure high-pressure stability and safety during heavy bolting operations:
High-Precision 100 Pressure Gauge
Provides exact, readable feedback across the 40–700 bar operating range.
Compact Three-Stage Flow
Maximizes fluid displacement speed during low-pressure advance/retract cycles and shifts automatically into high pressure.
High-Precision 100 Pressure Gauge, Multi-Wrench Expansion
Provides exact, readable feedback across the 40–700 bar operating range. Standard blocks accommodate 1 or 2 wrenches simultaneously, with manifold options available to drive up to 4 wrenches at once.
Aluminum Oil Tank & Thermometer
Lightweight fluid reservoirs equipped with visual oil level indicators and integrated thermometers.
THE POWER SOURCE BEHIND INDUSTRIAL SHUTDOWNS.
Operating a heavy bolting system requires absolute precision to prevent under-torquing or catastrophic flange blowout. The Boltorq BT-DC series simplifies complex joint assembly through an intelligent micro-processor workflow:
Refinery Turnarounds

Powering multiple square-drive and low-profile hydraulic wrenches during critical heat exchanger servicing.
Wind Energy Infrastructure

Delivering reliable 700 bar hydraulic pressure in remote tower construction environments.
Power Generation Facilities

Upon pressing the single operating trigger, the motor initiates a soft-start cycle, feeding smooth rotational force without placing a sudden impact jerk on the technician.
FREQUENTLY ASKED QUESTIONS ABOUT
hydraulic torque wrench PUMPS
Can the LP3 electric pump run continuously for 24 hours?
Yes. Thanks to its built-in efficient radiator and aluminum oil cooler, the LP3 series is engineered to support 24-hour continuous industrial operation.
How many torque wrenches can be operated simultaneously using the LP3-N4 model?
The LP3-N4 model supports up to 4 wrenches simultaneously using its multi-port oil output configuration (8 x 1/4″ NPT block).
Where can I request a commercial quotation or custom voltage configuration?
Contact Boltorq’s export sales desk directly at sales@boltorq.com or call +91 98927 03895.
What is the primary difference between the LP3 Electric and LP3-N Pneumatic hydraulic pumps?
The LP3 Electric Series runs on a quiet, high-torque 1.1kW 220V electric motor equipped with a radiator oil cooler for continuous 24-hour plant operation. The LP3-N Pneumatic Series utilizes a spark-free air drive (4-8 Bar air input), making it inherently explosion-proof and ideal for ATEX-rated hazardous oil refinery zones.
How does the automatic 3-stage flow system reduce bolting turnaround times?
The 3-stage valve automatically optimizes oil delivery based on live pressure resistance. During initial nut rundown, it delivers high oil flow (7-8.6 L/min) for rapid rotation. As torque builds, it seamlessly steps down through mid-stage (1.6-2.2 L/min) to high-pressure stage (0.8-1.1 L/min) up to 700 Bar (10,000 PSI).
Can Boltorq LP3 power packs drive multiple hydraulic torque wrenches simultaneously?
Yes. Both electric and pneumatic models are available in 2-tool output (4 x 1/4″ NPT) and 4-tool output (8 x 1/4″ NPT) configurations, enabling synchronized, multi-tool tightening for parallel flange compression.
What oil capacity and cooling mechanisms are included on the LP3 series?
All models feature a 5.5 Liter lightweight aluminum oil reservoir with an integrated sight level glass and thermometer. LP3 electric units come standard with an active electric radiator cooler to prevent thermal breakdown of hydraulic fluid during continuous high-cycle operation.
