    FlowServe PH6 Pump

    The PH6 diaphragm transfer pump is engineered for use with low and high viscosity fluids. Designed to fit virtually any container, the PH6 is the standard for many ag-chemical mini-bulk systems Capable of generating a maximum pressure of 1.7bar (25 psi), it is able to pump viscous chemicals even on the coldest mornings Its 12-volt motor is engineered to produce a flow rate of30 to 38 l/m (8 to 10 gpm) at 16°C (60°F) with a 30-minute duty cycle. For application flexibility, the PH6 may be vertically or horizontally mounted.

    EPDM vs VITON Seals

    EPDM seals are good in steam applications and offer excellent chemical resistance to a variety of acids and alkalines. Fairly good in ketones and alcohols. Not recommended for use in applications involving petroleum oils, strong acids, or strong alkalines. They have exceptionally good weather aging and ozone resistance. Temperature rating is from -20ºF to +225ºF (250ºF intermittent service).


    Viton® seals have excellent chemical resistance. They can be used in most applications involving mineral acids, salt solutions, chlorinated hydrocarbons and petroleum oils. They are particularly good in hydrocarbon service. Not suitable for steam or hot water service. Temperature rating is from -20°F to +300°F.
