Adhesive Dispensing Catalogue 2011

700 series pistons Pistons wipe the syringe insides as liquid is dispensed by a close tolerance fit. This eliminates air entrapment and fluid shear. Pistons are available in 3 styles to suit different liquid types. Three styles to fit all size barrels QTY

Pistons ensure that the pressure is evenly spread across the fluid surface to provide consistent dispensing. Wiper seal pistons prevent dripping and eliminate material waste by wiping the syringe barrel wall clean as fluid is dispensed. Maximum operating pressure is 100psi (6.9bar). Wiper pistons (white) are industry standard and a slightly tighter fit for use with low to medium viscosity fluids or with mechanical devices such as our TS700 series manual syringe gun to prevent leakage past the double wiping edges. New "Easy Flow" pistons (blue) are recommended for most general applications as they ensure no material residue is left on the syringe barrel walls while dispensing. Straight walled pistons (red) are recommended for reduced stringing and "bouncing" with high viscosity products.

7550LL1BPK Barrels and pistons are available in bulk value packs of 500 and 1000. When ordering, just add -500 or -1000 behind the above part numbers. Pistons are made of plastic and have dual blades to wipe the adhesive, paste or liquid from inside the syringe barrel as they move down. The blades also act to stop liquids from going past them as they dispense. Once a syringe has liquid inside, insert the piston and push down on one side. This will allow air to escape and ensures the piston sits directly on the fluid without an air gap. When bottom-filling a syringe using a barrel filler, the piston is pushed down to the base of the empty barrel and moves up as the liquid is fed into the syringe barrel. This method of filling is both quick and reduces air entrapment. Please see our range of syringe filling stations.
