Minor Maintenance Kit, Kinney KT 300 D

We put this list together based on what usually needs replacement. Here is exactly what you get :

Valves:

• 7 complete Discharge Valve Assemblies (066161)

The discharge valves are very important. They let gas leave the pump cylinder and stop it from flowing back in. Under normal use, the factory says you should replace these valves every year. When your pump is running properly, you should hear a sharp clicking sound. That clicking means the valves are working. No click? Time to check the valves.

Also, note that discharge valves are only sold as complete assemblies. You cannot buy just the spring or just the disc.

Seals:

• 1 Shaft Seal Head Assembly (1 7⁄8) (065215)

• 1 Seal Seat Assembly (065098)

These seals prevent oil leaks and vacuum loss. The shaft seal is critical for keeping oil inside the pump where it belongs.

Gaskets:

• 1 Separator Cover Gasket (807636)

• 1 Valve Deck Cover Gasket (808475)

These gaskets seal the main parts of your pump. Without good gaskets, you get leaks. Leaks mean loss of vacuum.

O-rings:

• 2 Buna O-rings, 110.72 x 3.53 mm (050245)

Buna-N rubber is the right material for vacuum pumps. It resists oil and handles heat well. These O-rings fit in specific grooves to create tight seals.

Backup Rings:

• 1 Backup Ring for Shaft Seal – Kinney (803423)

• 1 Backup Ring for Shaft Seal – Leybold Trivac (803422)

Backup rings support the seals. They stop the O-rings from moving or bending when the pump is under pressure.

Hardware:

• 21 Hex Head Cap Screws (052469)

These are the exact screws you need. No running to the hardware store to find the right size.

What is NOT in this kit?

This is a “Minor” kit. It is for routine maintenance, not a complete rebuild. If you need a full overhaul, you might want the Preventive Maintenance Kit (80970700BM)  or the Major Rebuild Kit (80970900BM) .

The Minor kit does not include things like:

• Bearings

• V-belt

• Cylinder gasket

• Sight glass or sight glass gasket

• Pistons, cams, or shafts

Those parts are in the larger kits.

Why buy the whole kit?

You could buy each part one by one. But that takes time. You might forget something. You might order the wrong size.

This kit saves you trouble. We have done the hard work for you. All the parts are matched to work together.

A little about the KT300D pump.

The KT300D is a popular, powerful pump. It pulls about 300 CFM at 60 Hz . It uses a 15 HP motor . The oil capacity is 10 gallons . It uses a triplex piston design. That means three pistons work together. This makes the pump run smoothly with almost no vibration .

These pumps have an integral positive pressure lubrication system. This ensures reliable lubrication at all pressure levels. They are water-cooled. The adjustable gas ballast valve is standard for handling water vapor .

People use these pumps for :

• Vacuum packaging

• Vacuum furnaces

• Vacuum coating

When should you use this kit?

Here are some signs that your pump needs maintenance:

• The pump is losing vacuum power

• You hear unusual noises

• You see oil leaks

• It has been running for many months without new valves or seals

Do not wait for a failure.

Regular maintenance is much cheaper than a full pump replacement. This Minor Kit gives you the parts you need for routine care. It is a smart investment in your pump’s life.
