Becker VTLF 400 Vanes

BECKER VTLF 400 REPLACEMENT VANES

VacAir supplies replacement carbon vanes for the Becker VTLF 400. Unlike the VTLF 2.400 and VTLF 2.500 models using this same vane, the VTLF 400 requires 10 WN 124-205 vanes for a complete replacement.

Each vane measures 220 × 88 × 6 mm and carries the VacAir replacement reference VA901373. For the ten-vane VTLF 400 set, the corresponding Becker OEM reference is 90137301010.

The replacement vanes are currently held in stock, giving VTLF 400 users the option of ordering individual vanes or the complete ten-vane quantity required by the pump.

The confirmed minimum wear height for WN124-205 is 60 mm. When existing vanes are removed during maintenance, the WN identification, physical dimensions and remaining height can therefore be checked before replacement.

REPLACING BECKER VTLF 400 CARBON VANES

The Becker VTLF 400 uses five rotor slots, each containing two carbon graphite vanes, giving a total of ten vanes. This paired arrangement makes it important to examine both vanes within each slot during routine maintenance. Differences in wear between neighbouring vanes, damaged running edges or restricted movement can indicate internal conditions requiring further investigation. New vanes have a height of 88 mm, with a confirmed minimum wear height of 60 mm.

VacAir Superstore stocks WN 124-205 replacement carbon vanes for Becker 90137301010, identified by VacAir reference VA901373. Each vane measures 220 × 88 × 6 mm (L × H × T). A complete VTLF 400 replacement requires ten vanes arranged as five pairs. Although this vane specification is shared with other Becker pumps, the ten-vane quantity is specific to this model’s configuration and must be observed when planning maintenance.

VTLF 400 VANE INSPECTION & FITTING PROCEDURE

1. Isolate and prepare the pump. Disconnect the electrical supply, prevent accidental starting and allow the VTLF 400 to cool. Make connected vacuum equipment safe and follow Becker’s maintenance instructions before opening the pump.
2. Remove and inspect all ten vanes. Carefully withdraw both vanes from each of the five rotor slots. Check every vane for cracking, chipped edges, uneven wear or missing sections. Measure the remaining height against the 60 mm minimum and compare the condition of the two vanes removed from each slot.
3. Inspect all five rotor slots. Shine a suitable inspection light along the accessible length of each slot, including the far ends. Examine both vane positions for deposits, scoring, damaged edges or obstructions that could prevent free movement.
4. Remove contamination and fragments. Clean the rotor slots, cylinder and accessible internal surfaces thoroughly. Account for all pieces of any fractured vanes. Controlled compressed air may be used where permitted by Becker’s instructions, with suitable dust control and protection. Avoid blowing debris further into the pump.
5. Check the new vane specification. Confirm WN 124-205 and dimensions of 220 × 88 × 6 mm. Each replacement vane must slide smoothly into its designated position without binding. Check both vane positions within every rotor slot and never force or tap a tight-fitting vane into place.
6. Position the first pair correctly. Fit the two replacement vanes into the upper accessible rotor slot in accordance with Becker’s instructions. Observe the correct orientation of each vane: the higher edge is the leading edge and the chamfer follows behind. Confirm that both vanes are correctly seated and move freely.
7. Rotate and fit the remaining pairs. Carefully turn the rotor by hand in accordance with Becker’s instructions, checking the movement of the installed pair. Continue fitting two vanes into each of the remaining four rotor slots until all ten replacement vanes are installed.
8. Complete the final inspection. Confirm that all five rotor slots contain two vanes each and that every vane moves freely. Check for remaining debris and inspect the cylinder, end plates, bearings, inlet filtration and cooling arrangements as appropriate. Investigate abnormal wear or damage before reassembling and testing the pump.

For planned servicing beyond the vane replacement, VacAir also supplies the Becker VTLF 400 service and maintenance kit. Please refer to the kit product page for its current contents and specification. Our experienced vacuum pump engineers can assist with vane fitting, fault investigation, scheduled servicing and complete pump repairs.

UK, EUROPEAN & WORLDWIDE SUPPLY

WHY BUY BECKER VTLF 400 VANES FROM VACAIR?

When buying replacement carbon vanes for a Becker VTLF 400, it is important to obtain both the correct vane specification and the correct number of vanes. VacAir Superstore has specialised in replacement vacuum pump vanes since 1996, supplying industrial customers who value accurate identification, competitive prices and knowledgeable assistance. We are vacuum pump specialists, not simply a general parts catalogue offering products without understanding their application.

Our knowledge of Becker equipment extends back decades. VacAir’s senior management has over 40 years of combined experience working for the former Becker UK agent, providing a substantial background in Becker vacuum pumps, replacement components and the requirements of industrial users. This experience helps us assist customers who may have a pump model number, an old vane marking or an OEM reference but need confirmation before ordering.

We hold replacement vanes in UK stock and can supply the complete ten-vane requirement for the VTLF 400. Customers can also obtain assistance with additional service components, including the dedicated VTLF 400 service and maintenance kit. For other repair or maintenance requirements, our wider Becker spare parts range is supported by experienced people who understand the equipment being serviced.

Price is important, especially when a pump requires ten replacement vanes rather than a smaller quantity. VacAir aims to offer competitive pricing without compromising on appropriate vane specification or customer support. Our Price Promise applies to qualifying comparable replacement carbon vanes offered by UK suppliers. The comparison must involve new, in-stock vanes for the same pump model and application, with comparable quality and specification. OEM products, clearance items, promotions, one-off deals and contract pricing are excluded, and requests must be made at quotation stage under our published terms.

Our approach to supply is equally practical. In-stock replacement carbon vanes ordered by 4pm on working days can be despatched the same day, subject to order confirmation and carrier arrangements. We also understand that machinery breakdowns do not respect normal despatch deadlines. If a VTLF 400 is out of service after 4pm, we encourage customers to telephone us. Where circumstances allow, we will move heaven and earth to explore an urgent despatch solution rather than simply leaving the requirement until the next working day.

The business operates under an externally audited ISO 9001:2015 certified quality management system, reflecting our commitment to consistent processes and customer service. We regard honest technical advice, dependable product identification and long-term customer satisfaction as important parts of our reputation. Our customers should be able to make purchasing decisions based on genuine information rather than manufactured endorsements or artificial ratings.

In addition to supplying replacement carbon vanes, VacAir has highly experienced OEM factory-trained engineers who can help customers with fitting, servicing, repair and overhaul work. Some businesses prefer to maintain their own VTLF 400 pumps, while others need specialist assistance when the pump is already dismantled or has developed a fault. Our engineering team can provide support on site or through our specialist workshop, with further details available on our Becker pump repair and servicing page.

We also understand that replacement vanes may be only one part of the maintenance requirement. If inspection reveals abnormal wear, contamination or internal damage, our familiarity with Becker vacuum pumps allows us to discuss possible next steps and identify other components that may need attention. Customers benefit from a supplier that can provide both the replacement parts and practical engineering knowledge.

VacAir supplies UK, European and worldwide customers, including OEMs, distributors, industrial maintenance departments and independent vacuum pump engineers. From an individual WN 124-205 vane to the complete VTLF 400 ten-vane requirement, our aim remains the same: provide the right components, knowledgeable service, competitive prices and reliable support from a specialist business with decades of experience.
