We recommend overhauling to maintain performance for a long time through inspection and maintenance.

At Shinmeiwa Industries and Shinmeiwa Aqua Tech Service, we are committed to our after-sales service business with the philosophy of "restoring equipment during overhaul as close as possible to its original delivery condition." In our own factories and technical centers, as well as at service-certified stores that meet our technical standards, we provide services that ensure "expectation, trust, and satisfaction" through advanced technology, delivering peace of mind and safety to our customers. In our overhaul case collection, we introduce examples of overhauls for key components such as the "shaft (main axis)" which is essential for pumps, the "impeller" which is vital for pump operation, and the "mechanical seal" that protects the pump. 【Inspection Items】 - Cables and Motors - Ball Bearings - Mechanical Seals - Impellers - Pump Casings For more details, please contact us or download the catalog.

basic information

【Case Study】 ○ The Key of the Pump: "Shaft (Main Axis)" → Corrosion and damage occur at the mechanical seal mounting area, compromising the sealing capability of the shaft. → Measure the balance of the shaft (shaft runout) to confirm there is no torsional strain, then apply thermal spraying to regenerate the corroded and damaged areas. ○ The Lifeblood of the Pump: "Impeller" → The disassembled impeller undergoes dynamic balance measurement as needed, and additional processing is performed based on the measurement results. → By ensuring the balance of the impeller, pump vibrations are reduced, minimizing the impact on the mechanical seal and ball bearings. ○ Protecting the Pump: "Mechanical Seal" → A crucial component that prevents water ingress into the motor. → Damage to the sliding surfaces due to aging can lead to water ingress failures. → During overhaul, the shaft is repaired, and the mechanical seal is replaced with a new one. ● For more details, please contact us or download the catalog.
