Technology Breakthrough: YDW Vertical Dry-Running Pump & CQF-Z Self-Priming Magnetic Pump Solve Two Major Global Corrosive Pump Operation Pain Points

BEIJING, July 14 (Beijing Time) — Two core innovative products from YDPumps’ R&D department, the CQF-Z self-priming magnetic pump and YDW vertical dry-running acid resistant pump, have obtained national utility model patents and passed long-term continuous operation reliability testing, addressing two long-standing technical bottlenecks troubling global anti-corrosion pump end users.

Traditional standard magnetic pumps (MP, MPH, CQF) cannot realize self-priming, requiring complex bottom valve and pre-filling pipeline layout, which increases construction costs and hidden leakage risks for underground liquid storage tank projects. The upgraded CQF-Z series adds an integrated self-priming chamber on the basis of CQF magnetic pump’s sealless fluoroplastic structure, realizing automatic liquid absorption without manual water filling, with stable self-priming height up to 4 meters, perfectly matching underground waste acid pools and remote chemical liquid transfer pipelines widely used in overseas factories.

Another widespread industry problem is pump damage caused by accidental empty running when liquid level drops sharply. Conventional horizontal self-priming pumps (YD series) still cannot bear long-time no-medium operation, while the newly developed YDW vertical pump adopts dual protection mechanisms of internal circulating cooling channel and wear-resistant self-lubricating silicon carbide bearings. Test data shows the pump can continuously operate safely for 30 minutes without liquid, completely avoiding emergency shutdown losses caused by tank liquid shortage in automated production lines.

Other supporting models form a complete technical matching system: MP low-flow compact magnetic pumps for laboratory and small circulation; MPH high-flow magnetic pumps for large-volume chemical mixing; CQF full fluoroplastic magnetic pumps for ultra-corrosive medium; YD coaxial self-priming pumps for conventional horizontal self-priming demands.

Industry technical experts pointed out that YDPumps’ technical iteration covering magnetic drive, self-priming and dry-running protection fills the gap of integrated multi-scenario anti-corrosion pump solutions in the global market. The six-series product technology combination provides a cost-effective alternative solution for global manufacturers to replace high-priced imported pumps from Europe, Japan and the United States, and drives the overall technical progress of the global acid & alkali resistant pump industry toward safety, energy saving and low maintenance.
