Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Industrial Pumps. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
The QSR-V is an industrial Roots vacuum pump presented for high-vacuum processing, including vacuum coating and metallurgy. The supplied information describes it as an oil-sealed, positive-displacement pump intended for dry working conditions and mainsuction duty.
The stated design combines high-volume operation with high pumping speed, stable performance, compact construction, low noise, and reliable operation. Listed industrial uses also include vacuum forming, dehydration, and extrusion. Customization is available, including sample-based customization.
Available information identifies a 40–350 mm specification range, wooden-box transport packaging, and a stated production capacity of 50 sets per month. Most standard models have a stated minimum order quantity of one set.
Standard products are stated to dispatch approxima ation is important before specification or purchase. The source data describes the product as both a Roots rotary vacuum pump and a reciprocating-structure vacuum pump, so the exact internal configuration should be resolved for the selected model.
Buyers should also request the precise model size, pumping-speed curve, attainable vacuum, motor and electrical requirements, inlet and outlet dimensions, oil specification, noise data, cooling method, materials of construction, included accessories, and installation requirements.
Confirm whether the stated 40–350 mm range refers to connection diameter, model size, or another measurement. The listed package dimensions and gross weight should also be checked against the selected configuration rather than assumed to apply to every version.
