Numerous industrial working scenarios require extracting corrosive liquid from underground waste‑liquid pools, low‑lying chemical storage tanks and sump pits. Ordinary horizontal pumps demand manual liquid‑filling before startup, which increases operating complexity and safety risks when handling toxic or corrosive media. Self‑priming corrosion‑resistant pumps become critical hardware for waste‑acid regeneration, flue‑gas scrubber chemical dosing and electroplating waste‑liquid transportation.
Yida delivers two core self‑priming product branches. CQF‑Z self‑priming magnetic‑drive pumps integrate magnetic‑coupling zero‑leak merits and built‑in self‑priming chambers. Represented by CQF‑Z40012, CQF‑Z40022, CQF‑Z50032 and CQF‑Z50052, this series eliminates mechanical shaft seals completely. It fits applications transporting volatile, poisonous high‑purity corrosive fluid, such as waste‑acid collection from chemical workshops and reactor raw‑material feeding.
YD‑series coaxial self‑priming acid‑resistant pumps adopt optimized Teflon elastic shaft‑seal structure, represented by YD‑40012, YD‑50052, YD‑80072 and YD‑80102 models. Acting as cost‑effective complementary solutions to magnetic self‑priming pumps, they provide stable self‑suction performance for medium‑corrosion media containing tiny solid particles, commonly deployed for wastewater‑treatment chemical‑dosing loops and plating waste‑liquid lifting tasks.
Wetted‑part materials support strong acid and alkali resistance, and full‑copper motor configuration guarantees high energy efficiency for continuous operation. With CE certification, the self‑priming pump product family serves chemical plants, environmental‑protection waste‑treatment facilities and new‑energy material factories in Europe, Southeast Asia, Middle East and other global regions. Plant engineering teams can choose sealless magnetic self‑priming type for strict zero‑leak requirements or shaft‑seal‑equipped YD series for cost‑sensitive projects with particle‑containing process fluid.
