High Performance DC Diaphragm low flow hearth and home furnace pump


TOPSFLO has rich experience in micro field, especially for fireplace, we have many cooperated clients in this industry use our pumps very well.



• Super low noise

As the indoor replace, super low noise is very important, TOPSFLO pumps work very silent, the clients have very satisfying feedbacks.

• 20- 350ml/min small & stable flow

As a key request of replace, the flow rate should be very small, we can offer 20-350ml/min,small ow diaphragm pumps; what's more, with high overall performance, the pump's ow rate can keep very stable, which is vitally related with the smooth & comfortable ame, the clients can enjoy themselves very well.

• Endurable material

The pump are made with high quality EPDM membrane & valve, which can pump >95% bio-ethanol very well.

• Compact size

With compact/tiny size, the pump easier to equip into the replace & makes the replace look delicate/beautiful.

• Long lifetime

Made by advanced brushless coreless motor, the pump's total accumulated lifetime above 15,000 hours, it is much more resistant compared with market's normal types. (3000hours high performance brush pump & 10,000 hours brushless pump are also available).
