Standard quotation cycle is 1-3 business days for standard models, and 3-7 days for custom or special specification requirements. Complex projects may require additional time for engineering review.

Required parameters for chemical pump selection: 1) Fluid chemical composition and concentration, 2) Operating temperature, 3) Required flow rate (m³/h or GPM), 4) Required head/pressure (m or bar), 5) Viscosity and solid particle content, 6) Installation type and environment.

Yes, raw material prices (especially plastics, metals, and motor components) directly impact pump pricing. Significant raw material market fluctuations may be reflected in product pricing adjustments.

Imported components (premium magnets, mechanical seals, motors) can increase price by 15-40%, depending on the component type and brand. They typically offer longer service life, better reliability, and wider availability of global service support.

Main price difference factors: material quality and thickness, motor brand (premium vs economy), manufacturing precision, quality certification standards, after-sales support, and R&D investment in product design and testing.
