Description
Product Summary
The Appion KTT881-R contains the seals, O-rings, vanes, valves, and springs needed to rebuild the internals of the Appion TEZ8 dual-stage vacuum pump. It is Appion's complete internal service kit for bringing a high-hour TEZ8 back to like-new pumping performance.
Worn vanes, tired shaft seals, and fatigued stage valves reduce pump speed and ultimate vacuum. The KTT881-R replaces the wear components in both stages, plus the oil pump, valve chamber, input, and output seals, so a single rebuild addresses the whole pump. Valve plates are not included.
Key Features
- Dual-Stage Vane Set: Two first-stage and two second-stage vanes for both rotors.
- Shaft Seals: Two shaft seals to stop oil seepage at the motor shaft.
- Stage Valves and Springs: First- and second-stage valves with four valve springs.
- Complete O-Ring Set: End plate, valve chamber, oil pump, brass input/output, input tree, and debris tube O-rings.
- Flare Cap Seals: 1/4", 3/8", and 1/2" flare cap seals for the intake caps.
- Alignment Hardware: Four steel dowel pins for accurate reassembly.
- Genuine Appion Part: Engineered for the Appion TEZ8 vacuum pump.
