High compression ratio for a steader flow and better efficiency
In Ragazzini pumps the piston stroke is longer than the diameter of the cylinder; this results in a high compression ratio and therefore an higher flow rate with a smaller number of revolutions. It is a pump with slower movements but a longer piston stroke. The whole mechanical part is thus improved, but in particular you obtain a more constant and compact flow, a greater self-priming capacity.
More efficient compensation to avoid any vibration and wear in the pipes
In Ragazzini pumps the dampeners have the shape and size that is most suitable for an uniform distribution of the high working pressure. They are placed directly on top of the suction and delivery pipes. In Ragazzini pumps the phenomenon generated by alternated pressures is already limited, but such an high compensation, so close to the pipes where the pressure is discharged, totally is eliminated.
More linear thrust to avoid mechanical wear and energy losses
The “sector” movement driven by a double support, common to all Ragazzini models, allows for the perfect alignment of the piston, thus providing the linear thrust necessary for the correct functioning of the piston gaskets and of the seals with Teflon gland rings.
Pumpex engine driven diaphragm pump DP3 - a compact unit on wheels, complete with gear box and a 4hp gasoline engine. The DP unit is totally self priming. The dry running capability and high percentage solids passage makes the DP3 suitable for seepage pumping of sludge and muddy water with high solids content.
Trouble free and easy handling
PUMPEX diaphragm pumps are perfect for muddy water, sludge or any water with high solids content. They are ideal for slow seepage applications or cleaning up the bottom (of sumps or tanks). The pump and engine are mounted together. It has handle and wheels so it can easily be moved to where it is needed, making installation and operation easy.
