IDENTIFYING BECKER VANE WN 124-120

Original Becker carbon vanes are commonly marked WN 124-120 on the vane edge. This marking can therefore be particularly useful when identifying a replacement vane removed from a pump.
WN 124-120 is a 63 × 36 × 4 mm carbon graphite vane used in a range of Becker DT, T and VT dry-running rotary vane pumps.

Becker OEM reference 90134700007 is a set of seven WN 124-120 vanes for the compatible Becker pump models listed on this page.

REPLACING BECKER WN 124-120 CARBON VANES

The Becker WN 124-120 carbon vane is fitted to a range of Becker DT, T and VT dry-running rotary vane pumps. These carbon graphite vanes are normal wear components and should be inspected during routine maintenance to help maintain pump performance and reduce the risk of unexpected production stoppages.

A new WN 124-120 vane measures 63 × 36 × 4 mm, with an original vane height of 36 mm and a minimum wear height of 21 mm. As the carbon wears, its remaining height decreases. Vanes approaching the minimum wear limit should be replaced as a complete set, with any unusual wear patterns investigated before new carbon is installed.

The compatible Becker DT 3.16, DT 4.16, T 3.16 DSK, T 4.16 DV, VT 3.16 and VT 4.16 pumps listed on this page each require seven WN 124-120 vanes. The corresponding Becker OEM reference is 90134700007. Confirm the pump model and vane marking before fitting replacements, particularly where the equipment has been in service for many years.

WN 124-120 maintenance inspection checklist:

✓ Remove and inspect all seven carbon vanes

✓ Measure each vane against the 21 mm wear limit

✓ Examine the carbon for cracks and chipped edges

✓ Compare wear patterns across the complete set

✓ Remove carbon dust from the rotor slots

✓ Inspect rotor and rotor shaft condition

✓ Check the cylinder for scoring or damage

✓ Examine bearings for wear or abnormal movement

✓ Inspect the inlet filter and relief valve

✓ Look for overheating or contamination

✓ Investigate abnormal or premature vane wear

✓ Check that each vane slides smoothly into its rotor slot without binding

CORRECT CARBON VANE ORIENTATION

When installing Becker WN 124-120 replacement carbon vanes, clean the rotor slots carefully and ensure that each vane moves freely throughout its working travel. Any remaining carbon fragments or deposits can restrict vane movement and contribute to premature wear or pump damage.

The higher edge of the vane is the leading edge. The chamfer follows behind the leading edge, as illustrated in the adjacent VacAir fitting diagram. Confirm the vane profile and correct orientation for the particular pump’s direction of rotation before installation.

Inspect the cylinder running surface, rotor slots, shaft and bearings before fitting the new seven-vane set. Where the previous vanes have broken, worn unevenly or suffered overheating, identify the underlying cause rather than simply replacing the carbon.

Always follow the relevant Becker manufacturer’s fitting and maintenance instructions. VacAir’s engineering team can assist with vane identification, professional fitting, pump servicing and mechanical repairs when required.

WN 124-120 wear limit: Original vane height 36 mm; minimum wear height 21 mm. The compatible Becker pumps listed on this page use seven vanes per pump. Replace the complete set when the wear limit is reached and investigate abnormal wear before fitting replacements.

Our experience helps customers obtain the correct quantity without the uncertainty sometimes associated with older pump models and part references.

More than 40 years of combined former Becker UK agent experience. Our senior team brings substantial first-hand knowledge of Becker vacuum pumps, their applications, internal components and maintenance requirements. We can help customers understand vane wear, filtration, fitting considerations and potential causes of abnormal pump operation. VacAir is a specialist vacuum pump business, not a generic catalogue seller with little knowledge of the machinery behind the part number.

Competitive prices and our genuine Price Promise. We aim to offer excellent value on high-quality replacement carbon vanes while retaining the benefits of specialist technical support. Our Price Promise allows qualifying lower prices from other UK suppliers to be considered for genuinely comparable replacement carbon vanes, subject to our published terms and conditions. Customers should not have to choose between competitive pricing and dealing with a knowledgeable supplier.

VacAir operates an ISO 9001:2015 certified quality management system, with externally audited processes supporting customer satisfaction, consistent service and continual improvement.

We have no need to. Our products, expertise and reputation have supported customers across the pump industry for decades.

OEM-trained engineers and dedicated Becker pump repair facilities. Our expertise extends well beyond supplying carbon vanes. VacAir’s engineers can fit replacement vanes, inspect rotor and cylinder condition, investigate mechanical problems and carry out servicing or repairs. Our Becker pump repair and refurbishment workshop provides customers with professional fitting, maintenance and mechanical repair support at highly competitive rates.

Becker spare parts, replacement alternatives and complete pump support. We stock a wide range of Becker vacuum pump spare parts, including OEM components and quality replacement alternatives. Customers can discuss additional maintenance requirements with a company that understands the complete vacuum pump, rather than dealing with separate suppliers for vanes, spares and technical assistance.

Reliable supply for planned maintenance and urgent breakdowns. Whether a customer is servicing a single Becker DT 3.16, maintaining multiple VT 4.16 pumps or carrying out repairs on older T-series equipment, our aim is to make the process straightforward. We combine UK vane stock, correct set quantities, practical technical knowledge, competitive quotations and UK or international delivery arrangements to help keep essential equipment operating.
