Many industrial‑site working conditions require pumping corrosive liquids from lower‑position storage tanks, sump pits or waste‑liquid pools, where conventional centrifugal pumps face priming obstacles. Self‑priming corrosion‑resistant pump series including CQF‑Z and YD fill this technical gap for global process‑industry users.
CQF‑Z self‑priming magnetic‑drive pumps combine magnetic‑coupling zero‑leak merits with built‑in self‑priming chambers. Without mechanical‑shaft‑seal assemblies, they handle volatile, toxic or high‑purity corrosive fluids, ideal for waste‑acid collection, chemical‑reactor feeding and underground‑sump‑liquid extraction. Representative specifications include CQF‑Z40012, CQF‑Z50052 and other models covering medium‑and‑large‑flow‑rate ranges.
YD‑series coaxial self‑priming acid‑resistant pumps adopt optimized Teflon elastic shaft‑seal structures. As cost‑effective complementary solutions to magnetic‑drive self‑priming pumps, they deliver reliable self‑suction capacity under moderate‑corrosion working media containing fine solid particles. The YD product range covers YD‑40012, YD‑50052, YD‑80102 and other variants to satisfy diversified flow‑demands.
Both product families deploy energy‑saving full‑copper motors and obtain CE conformity certification. Major application scenarios include environmental‑protection‑project waste‑liquid lifting, chemical‑pharmacy reagent dosing, plating‑shop waste‑solution transfer and industrial‑waste‑water circulation. Process engineers can select sealless magnetic‑drive variants for high‑safety‑critical working‑conditions or Teflon‑sealed self‑priming units for budget‑oriented projects. Diversified self‑priming pump portfolios help international EPC teams make targeted equipment selections facing varied site constraints.
