Separ Hand Priming Pump - 10666

  • No differential pressure drop
  • Compact size
  • High slow rate and lift capacity
  • Placed in suction line between filter and pump
  • Diesel and biodiesel (B100)
  • Can be mounted horizontally or vertically

The unique design of the Separ priming pump allows for an unrestricted flow of fuel through the pump in normal operation, then when needed, the main body is simply rotated to bring the priming pump into the fuel line.


This high capacity pump can therefore be left in-line and bought into and out of use as and when needed, providing the simplest way to prime your Separ fuel filter and fuel system.


Designed to seemlessly integrate with the Separ Evo-10 filter, this priming pump is ideal for generator, agricultural and industrial applications.

*Please note as this hand priming pump is made of plastic, it is not strictly suitable for marine use.
