A hand operated stirrup pump with a double chamber that allows a maximum of 5000cc (2 x 2500cc). The hand pump can also be downgraded to a single chamber (1 x 2500cc) - this will allow the pump to only work when pushed downwards, reducing the effort required to use the pump at higher pressures.
Constructed from a highly durable ABS plastic.
