FAQ – Nachi Piston Pump Wholesale & Supply
Q: Are these genuine Nachi pumps or aftermarket replacements?
A: We manufacture high-quality aftermarket alternatives engineered to meet or exceed OEM specifications. These are not genuine Nachi-branded products. They are dimensionally identical replacements built for direct interchange.
Q: What is the minimum order quantity?
A: MOQ varies by product type. Complete pump assemblies start at 1–2 units for trial orders. Replacement parts typically require 5–20 pieces depending on the component. We accommodate sample orders for quality verification.
Q: How do you ensure compatibility with my existing Nachi system?
A: We manufacture against original Nachi technical drawings and specifications. Provide your pump model number, and we confirm fitment including mounting dimensions, port sizes, shaft specs, and displacement. We can also work from your sample unit.
Q: What warranty do you offer?
A: All complete pump assemblies carry a 12-month warranty against manufacturing defects. Replacement parts carry a 6-month warranty. We maintain full traceability records for every batch.
Q: Can you supply in bulk for ongoing maintenance contracts?
A: Yes. We support annual supply agreements with fixed pricing, scheduled shipments, and dedicated inventory allocation. Many of our Nachi variable piston pump distributor partners operate on quarterly blanket orders.
Q: What payment terms are available?
A: T/T, L/C, and Western Union accepted. New customers typically start with 30% deposit / 70% before shipment. Established accounts may qualify for open terms based on order history.
