Product Description
CVC 35-inch diffusion pump for industrial high-vacuum systems
The CVC 35-inch diffusion pump is a large industrial high-vacuum pump originally produced by Consolidated Vacuum Corporation for applications requiring substantial pumping capacity.
Equipment references identify the large CVC PMC-32C design as a 35-inch pump that later became closely associated with the Varian HS-35 family after Varian acquired rights to the design. That makes this pump particularly relevant to facilities operating older CVC and Varian vacuum coating and processing equipment.
YTI currently has one CVC 35-inch pump available after rebuild for a purchase price of $18,500. Instead of purchasing an unknown as-is used pump, the available equipment can be evaluated and prepared for return to production.
The rebuild path can include teardown and cleaning, internal inspection, heater evaluation, seals and gaskets, appropriate diffusion-pump fluid, leak testing and operational verification. YTI can also review the connected chamber, baffle, high-vacuum valve, foreline and backing system when required.
Rental availability can also be discussed when temporary equipment is needed to reduce production downtime while another large diffusion pump is being serviced or replaced.

Rebuild Before Return to Service
What YTI can evaluate on this CVC 35-inch pump
01 · CLEAN
Pump teardown & cleaning
Remove old pump fluid, process contamination and residue from the pump body and internal components before inspection.
02 · INTERNALS
Inspect the jet assembly
Review the internal diffusion stages for damage, alignment, contamination and wear that could affect pump performance.
03 · HEATERS
Evaluate the boiler & heaters
Verify heater condition and output so the large boiler reaches and maintains the required operating temperature.
04 · SEALS
Reseal the pump
Replace required O-rings and gaskets so flange and service connections do not limit ultimate system pressure.
05 · FLUID
Install correct pump fluid
Refill the pump using the fluid type and charge appropriate to the equipment and intended application.
06 · VERIFY
Leak test & verify
Helium leak testing and operational verification help confirm the rebuilt pump before it returns to production.

CVC 35-inch diffusion pump questions
How much is the CVC 35-inch diffusion pump?
YTI’s purchase price for the CVC 35-inch diffusion pump is $18,500. The unit is available after rebuild. Freight and any application-specific requirements are confirmed before sale.
Does YTI currently have a CVC 35-inch diffusion pump available?
Yes. YTI currently has one CVC 35-inch diffusion pump available after rebuild for $18,500. Availability should be reconfirmed before purchase because industrial equipment inventory can change.
Is the CVC 35-inch pump available for rental?
Rental availability can be requested from YTI. Rental pricing is quoted separately and depends on rebuild status, timing, application and equipment configuration.
What model is the CVC 35-inch diffusion pump?
Historical equipment references identify a large CVC 35-inch diffusion pump as part of the PMC-32C family. YTI should confirm the nameplate and serial information of the physical inventory unit before representing an exact model designation.
Is this pump related to the Varian HS-35?
Historical vacuum-equipment references associate the CVC 35-inch PMC-32C design with the later Varian HS-35 family. Exact physical compatibility still needs to be verified against the actual pump and vacuum system.
What does “available after rebuild” mean?
The pump is currently a rebuild candidate rather than an as-is ready-to-install unit. YTI can evaluate the required cleaning, internal work, heaters, seals, pump fluid and testing before the unit is prepared for return to service.
Can YTI rebuild my existing CVC diffusion pump?
Yes. YTI supports customer-owned CVC diffusion pumps and can evaluate them for teardown, cleaning, internal inspection, heater work, seals, pump fluid, leak testing and refurbishment.
Can this pump replace a Varian HS-35?
It may be relevant to an HS-35 application because of the historical relationship between the CVC and Varian designs, but replacement should never be assumed from throat size alone. YTI should verify flange dimensions, overall height, foreline location, heaters, cooling, backing capacity and connected hardware.
What information should I send YTI before purchasing this pump?
Send the existing pump manufacturer and model, nameplate and equipment photos, inlet flange dimensions, foreline connection, heater information, chamber application, backing-pump model, target vacuum, available installation space and required timeline.
