Industry Overview
The metallurgy & mining industry covers the full industrial chain including underground mining, grinding & flotation, tailings transportation, smelting & slag treatment, pickling passivation, pit drainage and plant cooling water supply, featuring harsh working conditions. Conveyed media fall into two main categories: highly abrasive solid-liquid mixtures such as hard ore particles, high-concentration tailings, steel slag and red mud; highly corrosive fluids including hydrochloric acid, caustic soda, heavy metal extraction liquid and mineral processing chemicals. Pumps for mining sites must meet strict standards on wear resistance, anti-clogging performance, acid & alkali resistance, explosion-proof grade and stability for 24-hour continuous operation.

Industry Challenges
1. Heavy liquid level variation in deep tanks causes cavitation and dry suction of horizontal pumps;
2. Volatile corrosive liquid easily leads to seal leakage of horizontal pumps and excessive acid mist emission;
3. Standard submersible pumps are fully immersed in corrosive liquid, motors break down frequently, maintenance requires cranes and production shutdown;
4. For 24h continuous smelting process, horizontal pumps need manual priming on every restart with high labor attendance cost;
5. Narrow space of underground sealed tanks limits horizontal pump pipeline layout with high civil construction investment.

RFQ
Our metallurgical pickling workshop transports corrosive hydrochloric acid and caustic soda, leakage pollution is our big concern. Is vertical chemical sump pump applicable?
Fully applicable. The motor of FYH vertical chemical pump is installed above liquid level to avoid corrosion from acid mist. Optional 316 stainless steel or PTFE wetted parts resist strong acid & alkali, and the seal-free submerged design eliminates hazardous liquid spillage to comply with mine environmental standards.
Can FYH vertical chemical pumps transport high-concentration mineral slurry and tailings?
No. Vertical chemical pumps feature narrow flow channels and poor wear resistance, only designed for clean corrosive liquid without coarse solids. Hard ore particles will abrade impellers and clog the pump rapidly.
Our factory has several distributed sewage pits. Separate pump installation for each pit costs too much. Is it possible to adopt one pump for shared multi-point drainage?
ZW mobile self-priming sewage pumps with roller or trailer base and quick pipeline connectors are your best choice. One pump can serve multiple scattered wastewater pools alternately. Submerged pumps are fixed-installed and not suitable for multi-point alternating drainage, designed for long-term circulation of single storage tanks.
Do TA2 titanium pumps need a Dual-Use Item Export License when exporting to overseas metallurgical and mining projects?
Chemical pumps with TA2 industrial pure titanium wetted parts require Dual-Use Items and Technologies Export License prior to export in accordance with customs control regulations. Pumps made of ordinary 304/316 stainless steel or cast iron are not under control and can be declared for customs normally. We can provide complete material test reports to support customs clearance.
The oil pump will be installed in open-air mine oil depots. Can the motor reach BT4/CT4 explosion-proof grade?
BT4 and CT4 explosion-proof motors are optional with standard IP54 rainproof & dustproof rating, allowing direct outdoor installation without dedicated oil pump houses.
