TOPSFLO has extensive experience in many different applications. In order to make a better product recommendation, please tell us as much as possible about your application and how you intend to use the pump. Besides, flow, pressure, motor type and voltage, and liquid type must be considered when selecting a pump.

チューブが長いか制限されていると、高圧抵抗が発生します。これにより、ポンプ流量が減少したり、より多くの電力が必要になったりします。

We offer one warrantee period beginning from the time of shipment for OEM application, we can provide spare parts for replacements, if our serious product problems, we can make replacement of free charge.

TOPSFLO products are produced in accordance with the highest quality standards, and have passed the “Rheinland ISO9001” and “TÜV Rheinland 16949” system certifications.

Each product sold by our company has a unique traceability code, which can be identified and traced back to the production batch, time, incoming batch, testing records and other information. Our products are independently developed and designed, and 90% of the products are exported under our own brand. The appearance, labels and packaging of the products are all recognizable by the TOPSFLO Logo. Our products have their own unique design features, and are mainly for the middle and high-end market, which can be easily identified from the appearance and performance of product parts.

We have our own independent structural engineers, electronic engineers, electrical engineers, and process engineers. If the customer’s project must require some non-standard samples or additional customization, after the customer tests our standard products to confirm that the basic parameter performance is ok, we can customize structure/electronics/motor different customization requirements of customers.

Yes, of course, and Topsflo engineers will assist you in better installation. As a potential partner of your future business, it is our pleasure and duty to support your business with our best efforts.

Self-priming pumps evacuate air from the pump, allowing fluid to rise up and enter the pump. Gear pumps and diaphragm pumps have self-priming functions, but centrifugal pumps do not.

Centrifugal pumps generate centrifugal force through the rotation of the impeller to drive the liquid to run. The liquid level needs to be higher than the height of the pump impeller, so there is no self-priming function. Customers should take it into consideration when designing, pay attention to installation conditions, and we can provide suggestions if necessary. If the design must be self-priming, gear pumps or diaphragm pumps can be considered.
