Becker DVT 3.140 vanes

BECKER DVT 3.140 REPLACEMENT VANES

The Becker DVT 3.140 is a dry-running rotary vane vacuum/pressure pump using 7 carbon graphite vanes. VacAir supplies a complete replacement vane set manufactured to the correct 240 × 48 × 4 mm dimensions for this model.

The vane used in the DVT 3.140 is identified as WN 124-031. The Becker reference for the complete seven-vane set is 90133400007, with VacAir replacement reference VA901334.

We hold these vanes in UK stock and can also supply the filters, service kit and other spare parts required when carrying out maintenance on a DVT 3.140.

REPLACING BECKER DVT 3.140 CARBON VANES

The Becker DVT 3.140 uses seven carbon graphite vanes in its dry-running rotary vane mechanism. These wearing components should be inspected during routine maintenance, especially when the pump operates for extended periods or shows signs of reduced performance. New WN 124-031 vanes have a height of 48 mm and a specified minimum wear height of 31 mm. Cracked, chipped or unevenly worn vanes may require replacement before reaching that limit.

VacAir stocks WN 124-031 replacement carbon vanes for Becker 90133400007, reference VA901334. Each vane measures 240 × 48 × 4 mm (L × H × T), and a complete DVT 3.140 replacement requires seven vanes. Before fitting the new set, inspect the internal components carefully, particularly if the existing vanes have fractured or suffered abnormal wear.

DVT 3.140 VANE INSPECTION & FITTING PROCEDURE

1. Isolate and prepare the pump. Disconnect the electrical supply, prevent accidental starting and allow the DVT 3.140 to cool. Make the connected vacuum and pressure systems safe and follow Becker’s maintenance instructions before opening the pump.
2. Remove and inspect all seven vanes. Carefully withdraw the existing vanes, checking each for cracks, chipped edges, missing sections and uneven wear. Measure the remaining height against the 31 mm minimum wear limit. Account for broken pieces and investigate any unusually rapid or uneven wear.
3. Inspect the rotor slots. Use a suitable inspection light to examine the accessible length of each slot, including the far ends. Look for scoring, accumulated dust, damaged slot edges or deposits that could prevent the replacement vanes from moving freely.
4. Remove contamination and fragments. Thoroughly clean the rotor slots, cylinder and accessible internal surfaces. If a vane has fractured, locate and remove all fragments before fitting replacements. Use controlled compressed air only where permitted by the manufacturer’s instructions, with appropriate dust control, and avoid blowing debris further into the pump.
5. Check the replacement specification. Confirm WN 124-031 and dimensions of 240 × 48 × 4 mm. Check that each new vane slides smoothly into its intended rotor slot without binding. Never force a tight-fitting vane into position.
6. Fit the first vane correctly. Bring an accessible rotor slot into the upper fitting position and insert the first replacement vane according to Becker’s instructions. Ensure the higher edge is the leading edge and the chamfer follows behind. Check that the vane is seated correctly and moves freely.
7. Rotate and fit the remaining vanes. Carefully turn the rotor by hand in accordance with the manufacturer’s instructions, checking the movement of the fitted vane. Repeat until all seven replacement vanes are correctly installed and move freely within their slots.
8. Complete the final inspection. Confirm that all seven vanes are correctly fitted, slide freely and that no broken fragments remain. Inspect the rotor and shaft, cylinder running surface, bearings, inlet and exhaust filters, relief valve and accessible components as appropriate. Investigate abnormal wear or damage before reassembling and testing the pump.

For comprehensive maintenance, VacAir also supplies a dedicated Becker DVT 3.140 service and maintenance kit, containing seven replacement vanes, two 909507 inlet filters and one 909514 exhaust filter. Our experienced engineers can assist with vane fitting, pump servicing and repairs when additional technical support is required.

WHY BUY BECKER DVT 3.140 VANES FROM VACAIR?

VacAir Superstore has specialised in supplying replacement carbon vanes since 1996. We work with industrial maintenance departments, equipment manufacturers, vacuum pump service companies, distributors and businesses that rely on vacuum and pressure equipment every day. Unlike a general industrial catalogue supplier, our business is built around understanding vacuum pumps, identifying the correct replacement components and helping customers maintain their equipment reliably. We have spent decades supplying replacement carbon vanes and supporting customers with practical product knowledge.

Our senior management team has more than 40 years of combined experience working for the former Becker UK agent. This provides extensive familiarity with Becker pump construction, applications, vane specifications and maintenance requirements. When a customer needs replacement vanes for a Becker DVT 3.140, our understanding goes beyond matching an OEM part number. We appreciate the importance of correct dimensions, replacement quantities, internal pump condition and the practical requirements of keeping industrial equipment operating.

For the Becker DVT 3.140, VacAir stocks WN 124-031 replacement carbon vanes measuring 240 × 48 × 4 mm. The pump requires seven vanes, corresponding to Becker OEM reference 90133400007 and VacAir reference VA901334. Each new vane has a height of 48 mm, with a 31 mm minimum wear height. Our WN 124-031 replacement carbon vanes master page provides further identification information for the vane family and associated Becker references.

We maintain UK stock and supply the correct vane quantity for the pump model. For the DVT 3.140, that means supplying a complete seven-vane set rather than leaving customers to calculate quantities from a generic vane listing. Accurate identification helps avoid incorrect orders, unnecessary delays and the inconvenience of dismantling a pump only to discover that unsuitable components have arrived. Our team can assist when customers need to check vane markings, dimensions or OEM references before placing an enquiry.
