  • Diaphragm Liquid Dc Pump High Pressure Big Flow Rate - China

    price: contact company for price

    TF51- C

    Motor Type: Brushless DC motor

    Max flow rate: 3L/ Min

    Water lift: 6M

    Voltage: 6V 12V 24V

    Ideal Life Time: 10000 Hours

    â– Overview

    TOPSFLO micro diaphragm liquid / vacuum pumps are based on a simple principal, the circular power from the motor is converted into oscillating movement by aneccentric, which moves up and down its central point, this motion is then transferredto a diaphragm by means of a connecting rod, an elastic diaphragm, which in conjunction with an inlet and outlet valve creates a pumping action.

    The TF51 Series offers multiple component configurations allowing them to be used for either vacuum operation, liquid transfer, or alternating operations. The innovative, compact design incorporates leading edge technologies that allow it to operate harder, quieter and longer, reliabler, highly efficient.

    TF 51 pumps can be mounted in any position and can deliver up to 3 l/ min depending on the model and will operate against pressures of up to 6M.


    ● Small and powerful

    Micro design and maximum performance resulting from built- in technology are the outstanding characteristics of this product.

    ● Self- priming and excellent for pressure

    Sophisticated diaphragm technology and precise valve structures enable performances from 8.85 in . Hg suction and 14.5 PISG pressure.

    ● Dry running, durable and maintenance free

    The carefully considered design of these pumps allows them to be run dry and ensures safe operation and a long life even under the most severe conditions.

    ● Lasts Reliably Longer

    Using the advanced diaphragm elastomer and superior brushless motor design sets the highest benchmark for service- free operation that exceeds 10, 000 hours.

    ● Uncontaminated flow

    No contamination of the media due to oil- free operation

    ● Little vibration

    Because of leading edge technologies, top quality bearing, superior brushless motor

    ● High level of gas tightness

    thanks to stress- optimised structured diaphragm, newly- designed valves and sealing systems, precise placement of the pump head

    ● Extreme chemical resistance

    The use of chemically resistant materials optional such as PTFE FKM or other ,material combinations for the parts which allows the corrosive gas to be pumped.

    ● Optimal solution for your application

    A wide standard range of materials, motors , voltages configurates multiple components system selected


    The model code is identical to the order number, it is made up as follows:

    C Motor- Coreless Brushless DC Motor , lifetime 15, 000hours
