The Yamato GLD202BB220DPSKIT is the 220V oil-sealed rotary-vane vacuum pump kit with a stainless-steel (SUS) hose for the larger Yamato SDP vacuum drying ovens (SDP400/410 and SDP610). The stainless hose is the differentiator: it stands up to aggressive or condensable vapors that would attack a rubber line, making this the pump kit to specify when the drying load is chemically harsh rather than benign.

Application Profile
The GLD-202BB is the higher-displacement oil pump in Yamato's vacuum-oven line, sized for the 127 L SDP400/410 and 264 L SDP610 chambers whose larger volume and outgassing load need more pumping speed than the GLD-137CC provides for the small SDP/ADP ovens. What sets this kit apart from the rubber-hose kits is the stainless-steel hose: solvent vapors, acids and other reactive species that would degrade or permeate a rubber line are handled far better by SUS plumbing. Pairing the SUS hose with an inlet trap protects both the pump oil and the hose from condensable load.
As an oil-sealed pump it needs routine oil service, and — like the ovens it serves — it must never see flammable or explosive material.
Frequently Asked Questions
Which ovens does this kit fit? It is the 220V stainless-hose oil-pump kit recommended for the Yamato SDP410 and SDP610 vacuum ovens; the 115V twin is GLD202BB115DPSKIT.
Why the stainless hose instead of rubber? The SUS hose resists aggressive and condensable vapors that would attack a rubber line — choose it when your drying load is chemically harsh.
What pumping speed does it reach? The GLD-202BB is the larger of the two oil pumps in the line, but its exact pumping speed and ultimate pressure are not itemized in the current brochure — confirm with Yamato at quote.
Is there an oil-free alternative? Yes — the NEODRY dry-pump kit (NEOSDPKITC) fits all SDP models when oil-free operation is required.
Ordering & Configuration
Confirm at quote: supply voltage (this SKU is 220V), oven model (SDP410 / SDP610), and — if your process is aggressive — an appropriate inlet trap. Ask Yamato to confirm pumping-speed figures if they are decision-critical.
Warranty: Per Yamato standard terms — confirm coverage at quote.
Positioning: the GLD202BB220DPSKIT is the stainless-hose oil-pump kit for the larger SDP ovens — specify it over the rubber-hose GLD137/GLD202 kits when chamber size or vapor aggressiveness demands it, or step to the NEODRY dry-pump kit for oil-free work.
