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 BQG Series is an air-operated double-diaphragm pump range powered by compressed air. Its positive-displacement, self-priming design uses alternating pressure in the air chamber and one-way ball valves to move liquid forward.
The listed range includes models with nominal flow ratings from 100 to 500 L/min and outlet pressures from 0.2 to 0.45 MPa. Model selection depends on the required duty point and connection size. The 1.5-inch models cover listed flow ratings of 100, 140, 170 and 230 L/min.
The 2-inch group includes 125, 250 and 350 L/min models. Listed 3-inch options cover 200, 350, 450 and 500 L/min. Rated air pressure is 0.6 MPa across the model table, while stated air-consumption ranges vary by pump size.
Supported construction information identifies an aluminum-alloy pump body and PTFE diaphragm material. The product is described for mines, tunnels, tunnel engineering, petroleum and chemical industry duties.
Stated operating limits include fluid concentration below 15% by volume, suspended solids no larger than 9 mm, working temperatures from 5 to 50°C, medium temperature no higher than 50°C and medium pH from 6 to 8. The listed pressure range is 0.4–0.8 MPa.
Before procurement, confirm the exact model against the required flow and discharge pressure at the intended operating point. Buyers should also verify fluid identity, concentration, viscosity, solids content, chemical compatibility with every wetted component, suction conditions and available compressed-air capacity.
Confirm whether the stated pressure range refers to the required air supply for the selected model and request a complete model-specific performance curve.
Also confirm the final connection standard, installation orientation, dimensional drawing, net and packaged weight, noise requirements, included accessories and spare-parts scope.
If certification or hazardous-area compliance is required, obtain current documents for the exact model and intended installation;the available information lists ISO9001, CE and MA references but does not establish the precise certification scope for every variant.
Customization and a 12-month warranty are listed, so their exact coverage, exclusions and configuration impact should be documented in the purchase specification.
