Leybold 10770400V01 VACUBE VQ 400 i Oil-Sealed Screw Vacuum Pump

Variable-speed screw vacuum on demand: the VACUBE VQ 400 i

Leybold 10770400V01 is the VACUBE VQ 400 i in the front-panel version, the smallest size of the Leybold VACUBE VQ 400 to VQ 800 range. VACUBE is a family of intelligent single-stage oil-sealed screw vacuum pumps with variable speed drive (VSD) technology: the pump generates vacuum on demand, controlled and maintained by an internal controller, instead of running at full speed all the time. The maximum effective pumping speed of the VQ 400 is 420 m3/h (247 cfm).

The part number ends in V01, which marks the i model with a front panel. The same VQ 400 platform is also ordered as the iH version for high water vapour ingress (10770400V10) and with an HMI controller (V05 or V15), so the suffix decides what arrives on site.

Technical data for VQ 400 from the catalogue

Model suffixes and what they mean

The catalogue also describes iC and iCH versions: iC is designed for short-cycling applications such as packaging or electronics assembly lines, and iCH combines high water vapour tolerance with short-cycling ability.

Controllers, connectivity and accessories

Every VACUBE comes with an on-board controller. The MK5 controller offers setpoint pressure control, temperature management, gas ballast management, alarms and warnings, timers with a work period calendar and maintenance interval follow-up, and can be connected to a PLC through a fieldbus or read out over a local Ethernet connection. The Leybold VAControl controller adds remote monitoring through local access, Wi-Fi, LAN or cloud communication, diagnostics and energy efficiency views. For several pumps, the Multi-VAControl central controller (part number 10430001V01) synchronises up to 20 pumps and can manage a spare pump for redundancy, and up to 3 sensors can be connected.

Installation notes

• The catalogue gives installation requirements for the VQ 400 to VQ 800: keep the clearances shown for cooling air, which flows vertically through the pump.
• Operating ambient is 0 to 46 degrees C, which is broader than most oil-sealed pumps, but a GCC plant room should still be ventilated to stay inside the limit.
• At about 500 kg the pump needs lifting gear and a level floor; the footprint is described as pallet size for models up to 790 m3/h.
• The 380-460 V, 50/60 Hz supply and IP 54 enclosure suit indoor factory installation. For 200-230 V or 500-575 V networks the catalogue lists transformers.

Industries and uses

Applications printed for VACUBE include packaging (modified atmosphere and skin packaging, canning), food processing, woodworking and wood lamination, plastics thermoforming, glass forming and handling, print and paper, lithium-ion cell manufacturing, coating, pipeline drying and vacuum cooling. A pump that tracks demand with its variable speed drive saves power in plants where the vacuum load changes through the day.

Tell us the suffix you need (V01, V05, V10 or V15), the supply voltage and whether a central controller is wanted. More equipment is in the pumps category.

Selection and installation notes

A vacuum pump is selected from the pumping speed, the ultimate pressure and the gases or vapours it will handle. Use the oil grade the maker names, check the oil level before starting, connect the exhaust to a safe place and fit an oil mist filter where needed, use a trap or filter ahead of the pump for dust and vapour and warm the pump before pumping condensable vapour. Service the oil and filters on the schedule in the manual.

Information needed for a quotation

Send the full model code, the quantity, the delivery location in Oman or the GCC, the intended use and any accessories needed, so that the complete package can be quoted together.

Documents and supply information

The manufacturer data sheet is attached to this page and should be read together with the project specification and the site risk assessment before a purchase is confirmed. Ratings, standards and dimensions are quoted as printed on that sheet. Lead time, stock position and certificates available with the shipment are confirmed in the quotation, and we supply to Oman and the wider GCC region for industrial, utility and building services projects.
