Aftermarket replacement carbon vane set for Elmo Rietschle VTB 250, DTB 250, VTB 251, VTB 180, DTB 180 dry running (oil free) rotary vane vacuum pumps and compressors. It replaces Elmo Rietschle part number 526098 (also listed as 527958, 526623): a set of 5 graphite carbon vanes, each 320 x 69 x 5 mm (length x height x thickness).
In a dry running Rietschle pump the carbon vanes are the main wear part. They slide in the rotor slots, are thrown out against the cylinder wall and wear a little on every turn. As they shorten the pump loses vacuum and flow, runs hotter and gets noisier, and a vane worn too far can break and damage the cylinder. Rietschle gives a minimum vane height in each pump's manual; change the full set before the vanes reach it.
Always change all 5 vanes together so the rotor stays balanced, and clean the carbon dust out of the pump and filters while it is open. The vanes are made from self lubricating graphite carbon to the Rietschle size and come as a complete set for one pump.

Planned vane changes
Measure the vane height at every service and change the set before it reaches Rietschle's minimum for your pump. Keeping a spare set means the change happens at the service, not after a breakdown.
Falling vacuum or flow
If the pump takes longer to pull down, holds a weaker vacuum, or sheets and parts start slipping, worn vanes are the usual cause once the filters are clean.
Noisy or hot running
Short or chipped vanes chatter in the slots and the pump runs hotter. Stop and check the vanes before one breaks.
Typical machines
Rietschle dry running vane pumps run CNC router hold down tables, printing and paper handling machines, packaging machines and pneumatic conveying.

No. It is an aftermarket set made to the size of the Elmo Rietschle 526098 vanes. It is not made by or affiliated with Elmo Rietschle; the Rietschle numbers are used only to show what it replaces.
Yes if your pump is a Elmo Rietschle VTB 250, DTB 250, VTB 251, VTB 180, DTB 180 and the old vanes measure 320 x 69 x 5 mm. Check the model plate on the pump and measure an old vane before ordering.
The rotor in these pumps has 5 slots. Change every vane at the same time; mixing new and worn vanes unbalances the rotor and wears the new vanes fast.
When the vanes are worn down to the minimum height in your pump's manual, or sooner if a vane is chipped or cracked. Measure them at every filter service.
Clean the carbon dust from the pump housing, rotor slots and filters, and change the inlet and outlet filters if they are loaded. Fit the vanes the same way round as the old ones, with the bevelled edge against the cylinder wall.
