The Yamato GLD137CC220DPRKIT is the 220V oil-sealed rotary-vane vacuum pump kit matched to Yamato SDP and ADP vacuum drying ovens. It pairs the ULVAC GLD-137CC pump — 162 L/min at 60 Hz with a 0.67 Pa ultimate pressure — with the rubber hose connection kit needed to plumb the pump to the oven's KF/vacuum port. It is the vacuum source that turns a vacuum oven into a working system: pull the chamber down, dry heat-sensitive material gently at low pressure, and hold the level shown on the oven's digital vacuum gauge.

Application Profile
Vacuum drying lowers the boiling point of trapped solvent and moisture so material dries at a gentle temperature it could never tolerate at atmospheric pressure — the reason the SDP/ADP ovens exist. That only works if the pump can reach and hold a deep enough vacuum against the chamber's outgassing load. The GLD-137CC is an oil-sealed rotary-vane pump sized for the smaller SDP (47 L) and ADP (10–27 L) chambers, reaching 0.67 Pa so the oven can pull well into its working range. The rubber hose kit is the correct plumbing for these ovens; a stainless (SUS) hose variant exists for aggressive vapors on larger chambers.
Because it is an oil-sealed pump, plan for oil changes and use an inlet trap when drying corrosive or condensable vapors. Never pull vacuum on flammable or explosive material — the oven and pump are not explosion-proof.
Frequently Asked Questions
Which ovens does this pump kit fit? It is the 220V oil-pump kit recommended for the Yamato SDP310 vacuum oven and the ADP benchtop vacuum ovens; the 115V twin is GLD137CC115DPRKIT.
What vacuum level does it reach? The GLD-137CC reaches an ultimate pressure of 0.67 Pa (gas-ballast valve closed), with 162 L/min pumping speed at 60 Hz.
Rubber hose or stainless hose — which is this? This is the rubber hose kit. For aggressive or condensable vapors, Yamato offers stainless-hose kits (e.g. the GLD202-BB SKITs) on the larger SDP models.
Is it oil-free? No — it is an oil-sealed rotary-vane pump. For an oil-free option, see the NEODRY dry-pump kit (NEOSDPKITC).
Ordering & Configuration
Confirm at quote: supply voltage (this SKU is 220V) and that the pump matches your oven model (SDP310 / ADP). Order oil and an inlet trap if you dry condensable or corrosive vapors.
Warranty: Per Yamato standard terms — confirm coverage at quote.
Positioning: the GLD137CC220DPRKIT is the entry oil-pump kit for Yamato's small vacuum ovens — 162 L/min, 0.67 Pa, rubber hose. Step up to a GLD202-BB kit for the 127 L SDP400/410, or the NEODRY dry-pump kit when you need an oil-free vacuum source.
