Becker VX 4.40 vanes

BECKER VX 4.40 REPLACEMENT VANES

VacAir supplies replacement carbon vanes for the Becker VX 4.40. The VX 4.40 requires 7 WN 124-244 vanes when replacing the complete vane set.

Each replacement vane measures 95 × 41 × 4.3 mm and has a stated minimum wear height of 28 mm. The minimum height provides a useful reference when the existing carbon vanes are removed and measured during pump maintenance.

The current Becker part number is 90140900007. Earlier Becker documentation and parts records may show the previous reference 90139700007. VacAir supplies the replacement vane under our reference VA901397.

WN 124-244 replacement vanes are currently held in stock. VacAir can also supply the dedicated VX 4.40 maintenance kit and other spare parts for the pump, backed by technical and servicing support.

REPLACING BECKER VX 4.40 CARBON VANES

The Becker VX 4.40 dry-running rotary vane pump requires seven WN 124-244 replacement carbon vanes for a complete vane change. Each vane measures 95 × 41 × 4.3 mm (length × height × thickness), with a stated minimum wear height of 28 mm. When servicing the pump, inspect all seven vanes and investigate any unusual wear, damage or variation between them.

The current Becker OEM reference for the seven-vane set is 90140900007, replacing the previous reference 90139700007. VacAir supplies the replacement vane under reference VA901397. Both Becker references may appear in service records, previous invoices and older spare-parts documentation.

VX 4.40 VANE INSPECTION & FITTING PROCEDURE

1. Isolate the pump. Disconnect the electrical supply, prevent accidental starting, safely isolate connected pipework and allow the VX 4.40 to cool. Follow the applicable Becker maintenance instructions before opening the pump or accessing the rotor.
2. Remove and inspect all seven vanes. Carefully remove the complete carbon vane set. Check for cracks, chips, scoring, uneven wear or missing sections. Measure the remaining vane height against the stated 28 mm minimum wear height and investigate any abnormal differences between vanes.
3. Inspect the rotor slots. Check the full accessible length and depth of each rotor slot, including the far ends, for scoring, deposits, damage or restrictions that could interfere with free vane movement.
4. Remove all debris and fragments. Clean the rotor slots and accessible internal surfaces using methods permitted by Becker’s maintenance instructions. If any vane has fractured, ensure that all fragments and debris have been removed before fitting the replacement set to avoid damaging the new vanes.
5. Confirm the correct replacement vanes. Check the WN 124-244 identification, the 95 × 41 × 4.3 mm dimensions and the quantity of seven. Each new vane should slide smoothly within its rotor slot without being forced.
6. Check the vane orientation. Follow Becker’s maintenance instructions and the specified vane profile. Where the vane has a higher leading edge and a trailing chamfer, the higher edge is the leading edge and the chamfer follows behind in the direction of rotation. Never force a vane that binds or catches.
7. Fit the complete replacement set. Rotate the rotor carefully by hand as permitted by Becker’s instructions and install all seven carbon vanes. Check that each is correctly seated, properly orientated and able to move freely.
8. Carry out final inspections. Inspect the cylinder running surface, rotor, shaft, bearings, inlet and exhaust filtration and other accessible service components as appropriate. Investigate any scoring, damage or abnormal wear before reassembly and testing in accordance with the manufacturer’s instructions.

UK, EUROPEAN & WORLDWIDE SUPPLY

WHY BUY BECKER VX 4.40 VANES FROM VACAIR?

VacAir Superstore has specialised in replacement carbon vanes since 1996. We supply maintenance engineers, industrial pump users, resellers, service companies and OEMs who need correctly specified replacement vanes at competitive prices. Our experience extends beyond supplying spare parts: we understand the pumps, the maintenance requirements and the importance of keeping production equipment operational.

Our senior management team has more than 40 years of combined experience working for the former Becker UK agent. This provides substantial knowledge of Becker pump designs, vane specifications, part-number changes and servicing requirements. Customers benefit from speaking to specialists familiar with both current and older Becker equipment.

For the Becker VX 4.40, VacAir supplies seven WN 124-244 replacement carbon vanes, measuring 95 × 41 × 4.3 mm, with a stated minimum wear height of 28 mm. Our replacement reference is VA901397.

We recognise both the current and previous Becker OEM references. The current seven-vane set number is 90140900007, replacing 90139700007. This is particularly useful when customers are working from older service manuals, previous supplier invoices or historic spare-parts lists. We can help identify the correct replacement specification using either reference.

UK stock and the correct model quantity are important advantages. VacAir holds VX 4.40 replacement vanes in stock and understands that the pump requires a complete set of seven. We can assist with checking the WN identification, dimensions, OEM references and quantity before quotation and despatch.

Customers can also obtain the dedicated Becker VX 4.40 service and maintenance kit, together with additional Becker spare parts and engineering assistance. This makes VacAir a practical single point of contact for routine vane replacement and more extensive pump maintenance.

Our competitive pricing is backed by the VacAir Price Promise. We aim to provide excellent value on correctly specified replacement carbon vanes. Where another UK supplier offers a comparable new, in-stock replacement carbon vane for the same pump model and application, with comparable specification and quality, customers can request a price comparison at the quotation stage.

The Price Promise applies to replacement carbon vanes only. It excludes OEM products, clearance items, promotional offers, one-off quotations and contract pricing. Any comparison must meet the applicable conditions and be raised before the quotation is accepted.

Order by 4pm – same-day despatch is available for in-stock replacement carbon vanes on working days, subject to order confirmation and carrier availability. We supply customers throughout the UK, Europe and worldwide. If an urgent enquiry arrives after 4pm, we make exceptional efforts to investigate possible despatch and delivery arrangements without guaranteeing a service that may no longer be available.

VacAir operates within an externally audited ISO 9001:2015 certified quality management system. Accurate parts identification, consistent procedures, customer satisfaction and straightforward technical advice are central to our approach. We have built our reputation through decades of supplying and servicing industrial vacuum pumps.

Our highly experienced OEM factory-trained engineers can assist with replacement vane fitting, pump servicing, fault diagnosis, repairs and complete workshop overhauls. We support customers carrying out their own maintenance as well as those requiring professional engineering assistance.

During VX 4.40 vane replacement, correct inspection matters as much as correct part identification. Worn or fractured vanes should prompt examination of the rotor slots and accessible internal components, with all broken fragments removed before the replacement set is installed. The new vanes should be correctly orientated and move smoothly within their slots, following Becker’s maintenance instructions.

From our Leeds premises, VacAir supplies replacement carbon vanes, service kits, filters and Becker pump spare parts throughout the UK, Europe and worldwide. We combine UK stock, competitive pricing, specialist pump knowledge and experienced engineering support to help customers reduce downtime and maintain reliable operation.
