I'm looking for a reliable supplier of centrifugal pumps for an upcoming project. We need pumps that can handle various flow rates and pressures, so please provide specifications, availability, and any certifications the products might have. Additionally, it would be great if you could include details on pricing, bulk order discounts, and lead times for delivery. Any insights into your production capacity and quality assurance processes would also be appreciated, as we're aiming for a long-term partnership with the right manufacturer.
