About Inpro
Inpro is a manufacturer of gas regulation and oil supply equipment for industrial burner systems, lubrication circuits, and fluid-handling applications. The product range spans pressure regulators, fuel transfer units, tank monitoring systems, filtration cartridges, and emergency access components—primarily serving plant maintenance teams operating heating systems, burner installations, and centralised oil-supply networks. Inpro equipment is engineered to ISO and EN standards, with documented specifications on operating pressures, flow rates, filtration grades, and environmental ratings. The gas regulation line includes cabinet-mounted assemblies (such as the GAZ70009 and GAZ70011 models) with transparent inspection windows and emergency hammer-and-chain access tools. The oil supply family comprises self-priming gear pumps (MR-5U), low-pressure burner fuel units with integral regulation (VD2 LR-2.2 series), suction-line and return-line pumps (VDU5L23), diesel filters with stainless-steel mesh cartridges (Series 202), and tank-level monitoring systems (TANKALERT SMS) with ultrasonic sensing, IP67 enclosure rating, and GSM/GPRS remote notification. Inpro components are rated across defined pressure ranges (typically 2 bar return-line maximum for oil pumps), rotation speeds up to 3500 rpm, and filtration tolerances from 44 µm to 150 µm mesh. 3G Electric stocks 69 SKUs from the Inpro catalogue with same-day availability from the Woodlands warehouse, supporting global distribution to plant engineers, maintenance managers, and procurement teams.
Frequently asked questions
Common questions about Inpro from 3G Electric.
What is the maximum operating pressure for the Inpro VD2 LR-2.2 and VDU5L23 pumps?
Both the VD2 LR-2.2 low-pressure burner fuel unit and the VDU5L23 oil supply pump are rated to a maximum 2 bar return-line pressure. The VD2 LR-2.2 includes integral pressure regulation; the VDU5L23 operates at up to 3500 rpm with a 150 µm nylon mesh strainer and G1/8" nozzle port. Return-line pressure management is critical in burner fuel circuits to prevent overpressure in suction lines.
What filtration grades does the Inpro Series 202 diesel oil filter offer?
The Series 202 filter is supplied with a stainless-steel mesh cartridge rated to 100–44 µm, delivering 105 cm² of filtering surface. The cartridge code 20201/c1 is also available as a standalone sieve element with 100 µm filtration grade and a reference fluid viscosity of 1.5° Engler. Maximum working pressure is 1 bar on plastic housings. Suitable for diesel engine oil supply and industrial hydraulic pre-filtration.
How does the Inpro TANKALERT SMS tank alarm measure oil level, and what is its accuracy?
The TANKALERT SMS uses ultrasonic sensing with ±1 cm precision across a measurement range of 12 cm to 3 m at a 30° angle. It is rated IP67 and operates via tri-band GSM/GPRS connectivity for remote tank-level reporting. Storage temperature range is −30 °C to 60 °C. Designed for oil tank installations where condition monitoring and alert notification are required without manual gauging.
What standards do Inpro oil pumps and fuel units comply with?
Inpro oil supply components, including the VD2 LR-2.2 fuel unit, are manufactured to EN 225 and ISO 228/1 standards. EN 225 governs automatic oil burner fuel-supply units; ISO 228/1 covers pipe threads. These standards ensure compatibility with standard burner control systems and fuel-circuit connections across industrial heating installations.
Is the Inpro MR-5U fuel transfer unit self-priming, and what fluids can it handle?
Yes, the MR-5U is a self-priming gear pump with integral safety valve and 3/4" NPT connections. It is rated for fuel oils, lubricants, and animal and vegetable greases. Self-priming capability allows operation without pre-filling the pump case, reducing setup time in mobile or temporary fuel-distribution applications. The integrated safety valve protects against overpressure.
What emergency access components does Inpro provide for gas regulation cabinets?
Inpro supplies hammer-and-chain emergency access tools (SKU GAZ70010) and plexiglass inspection windows (SKU GAZ70012) for gas regulation cabinet models GAZ70009 and GAZ70011. These allow plant personnel to quickly shut off gas supply and visually inspect regulator status in emergency situations without disassembling the cabinet.
