Yes, it can. However, the following points must be considered:

• Pump body materials: Stainless steel or plungers/cylinder liners with corrosion-resistant coatings should be selected
• Sealing materials: Fluororubber (FKM) or polytetrafluoroethylene (PTFE) seals must be used to prevent chemical corrosion
• Post-operation cleaning: After construction, the pump body and pipelines must be flushed with clean water to prevent grout solidification and blockage

Slight vibrations are normal and result from the plunger's reciprocating motion. However, abnormally severe vibrations may indicate a problem, which might be caused by:

• Unstable foundation or insufficient fixation of the pump: Reinforce the base
• Wear of transmission components (crankshaft, bearings): Check lubrication and worn parts
• Excessive pressure pulsation: Install a pulsation damper (accumulator)

• Thorough cleaning: Circulate clean water through the pump body and pipelines until the water discharged is clear
• Drain residual grout: Open the drain valve to prevent residual grout from solidifying
• Lubrication: Apply lubricant to moving parts such as plungers and crankshafts
• Anti-corrosion protection: For long-term shutdown, apply anti-rust oil and cover the equipment with protective shielding

Before delivery, all of our equipment, such as grouting pumps, water injection pumps, pressure washers, drilling rigs, etc., is strictly tested in accordance with regulations to ensure compliance with design requirements. In addition, prior to packaging, all main components and accessories are checked for completeness, and all technical documentation is verified.

We implemented strict control measures during production, including:

• Non-conforming raw materials are not stored or used in production.
• Non-conforming parts are not transferred to the next process or stored.
• Non-conforming components are not assembled.
• Non-conforming products are not permitted to leave the factory.

All production processes strictly follow the technical drawings, manufacturing procedures, and technical requirements. Components may only proceed to the next stage only after passing inspection.
Final inspection and commissioning are carried out by specialized inspectors in accordance with product technical specifications. Each item must pass the inspection and be properly documented before a product qualification certificate is issued.
