[Delivery Example] Transporting phosphoric acid with a submersible pump

Identifying the cause of the failure through hearing and making proposals! Case study of the delivery of corrosion-resistant underwater pumps.

We received a request from a chemical plant stating, "We would like to transfer wastewater containing high concentrations of phosphoric acid from the process storage tank using a submersible pump." Since they prefer a solution without major construction and with a float switch on a 100V single-phase system, we proposed our corrosion-resistant submersible pump model LC-251-S. They mentioned that a flow rate of about 10L/min would be sufficient, but since the pump is somewhat over-spec, we suggested adjustments using a discharge-side valve. 【Case Overview】 ■ Issues - They want to transfer wastewater containing high concentrations of phosphoric acid from the process storage tank using a submersible pump. - The currently used submersible pump quickly suffers from impeller corrosion and failure due to acid. ■ Proposal - Adopt our corrosion-resistant submersible pump model LC-251-S. - Since the pump is somewhat over-spec, we suggested adjustments using a discharge-side valve. *For more details, please refer to the PDF document or feel free to contact us.
