Import All-Flo Diaphragm Pump — Buy in wholesale FOB from Supplier in China

A&S Pump Co., Ltd. supplies genuine ALL-FLO air-operated double diaphragm (AODD) pumps in sizes from 1/4 inch through 3 inches, covering the A025, C038, A050, C050, S050, A075, A100, S100, A150, A200 and A300 series. Representative catalogue numbers include the A025-SQP-GTPN-Y70 in the 1/4 inch range, the C050-SPP-SSPE-G70 in the 1/2 inch range, and the A200-C33-GG3N-B70 in the 2 inch range. The pumps are constructed with aluminium, stainless steel and polypropylene wetted-path options depending on the series and model code suffix.

ALL-FLO pumps use a reciprocating diaphragm mechanism powered by compressed air, eliminating seals and packing to give seal-less handling of abrasive, viscous or shear-sensitive fluids. Typical wet-end materials for standard industrial units include 316 stainless steel, aluminium and polypropylene, with elastomer choices of Buna-N, Viton, EPDM, PTFE and Santoprene to match chemical compatibility requirements. The pumps handle solids passage up to 6.4 mm in larger sizes and self-prime from dry to 5 metres. Typical air supply pressure ranges from 1.7 to 8.6 bar, with flow rates scaling from 15 litres per minute on the A025 to over 500 litres per minute on the A300 series.

These pumps serve chemical processing, paint and coatings, ceramic slip transfer, mining slurry, wastewater treatment and oil and gas sectors. Buyers sourcing through A&S Pump Co., Ltd. should confirm the exact wetted material combination, elastomer grade and port thread specification for their application, as the catalogue covers multiple configurations under each series code. The supplier also lists comparable diaphragm pumps from Ingersoll Rand, Yamada, Wilden, Sandpiper, Graco Husky and other major brands, indicating cross-reference capability for replacement or upgrade projects.

A&S Pump Co., Ltd. is located at 2nd Floor, Xinhe Linghang Building, Xingsheng Road, Gaoxing District, Chengdu 610000, Sichuan Province, China. The supplier carries a harbour trust tier and an imported supplier classification, with a listed response rate of 0.00 percent and no recorded average response hours. These signals suggest limited platform engagement history; buyers should initiate direct contact to gauge responsiveness and quotation turnaround.

The company positions itself as a multi-brand pump trading and sourcing operation rather than a captive manufacturer. Its catalogue extends beyond ALL-FLO to include Ingersoll Rand, Nitto Kohki, Yamada, BINKS Gemini, Seko, Ilmvac, Blagdon, Wilden, Shurflo, Wagner, Sandpiper, Versa-Matic, DEPA, KNF, Thomas and Graco Husky diaphragm pumps. No manufacturing certifications, factory audit data, revenue figures or employee counts are stated in the profile. Buyers should verify whether A&S Pump Co., Ltd. holds inventory in Chengdu or operates on a mill-order basis, and whether it provides after-sales spare diaphragm kits and technical documentation.
