Questions & Answers

Can you customize products to my specifications?

Absolutely. We provide OEM/ODM services and can manufacture according to your samples or technical drawings.

How quickly can you deliver products?

For in-stock items, we can ship within 3 days. For custom or non-stock items, delivery usually takes 7–15 days. We’ll confirm exact timing based on current inventory.

Is there a minimum order quantity?

Yes, but it’s flexible. Spare parts often have an MOQ of 1 piece, while complete pumps or motors vary by model—please inquire for details.

Are you a factory or a trading company?

We are a hybrid—both a manufacturer and a trading company. We produce our own products and also source specific components to offer complete solutions.

How do you ensure product quality?

We follow strict quality control protocols. All parts undergo CNC machining and heat treatment, and each is 100% tested before delivery to guarantee precision and reliability.

What payment methods do you accept?

We accept T/T, L/C, Western Union, Alibaba Trade Assurance, and VISA. For new customers, we usually require full prepayment or a 30% deposit with the balance due before shipment.

What shipping methods are available?

We offer flexible shipping via express carriers (DHL, FedEx, UPS) and sea freight (CIF/FOB). We can also deliver to your designated freight forwarder in China.

What is the warranty period for your products?

All products come with a 1-year warranty, provided they are installed and operated under normal conditions.
