Do you support prototypes and small-batch orders?

Yes. Prototype and small-batch production can be evaluated before volume production. MOQ and lead time depend on material, tooling and process complexity.

How do you protect customer drawings and designs?

Customer drawings, 3D models and technical information are managed confidentially. An NDA can also be signed when required.

Product Q&A

Q:What causes an impeller to vibrate during operation?

Impeller vibration may result from imbalance, dimensional deviation, improper shaft fit, uneven blade geometry, wear or incorrect installation. The actual cause should be evaluated together with the pump structure and operating conditions.

Q:How should I select the right impeller type for my pump?

Selection depends on the fluid, solid content, viscosity, flow rate, pressure, rotational speed and pump structure. The original drawing or approved sample should be used for final confirmation.

Q:Can an impeller be used with any pump casing?

Not always. Tooling requirements depend on the impeller structure, dimensions, manufacturing process and order quantity. We will evaluate the most suitable solution before quotation.

Q:What information affects impeller service life?

Material compatibility, fluid corrosiveness, abrasive particles, rotational speed, operating temperature, cavitation and installation accuracy can all affect service life.

Q:Can Tianhui manufacture an impeller from an existing sample?

Yes. We can evaluate the sample's dimensions, material and manufacturing feasibility, then confirm the requirements through a drawing or approved sample.
