505L pumphead
The twin offset track design of the 505L utilises 2.4mm wall double-y tube elements to overcome pulsation for accurate
dosing and dispensing. The 505L accepts Silicone and Marprene tubing up to 9.6mm bore giving a potential flow rate of
2400 ml/min per pumphead. (Fit the 505LX for flow rates up to 4800ml/min). Use 2.4mm wall tube for transfer for the
highest performance and improved viscous fluid handling.
Alternatively the 505L will run with two separate tubes although some channel to channel variance and minimal pulsation
may be experienced. For separate tube fitting or twin tube inlet to single tube outlet fitting tube clamping blocks must be
used.
505L Installation
Remove the mounting plate cover from the 505L. Align the drive shaft dog and 505L centre shaft slot and push the
pumphead on to drive. Tighten top and bottom mounting plate screws.
505LX Installation
Remove the 505L bowed front plate by undoing the two retaining screws (inside front face of 505L). Grease drive dog of
505LX. Align 505LX drive dog and 505L slot in centre shaft. Locate 505LX to 505L. Tighten the fixing screws at the mating
faces of the 505L and 505LX. Locate the bow front onto the 505LX and fit using the two retaining screws (inside front face
of 505LX).
