When the first grandson arrives, any grandfather knows he now has the chance to fulfill the dreams he had as a boy. A Formula 1 racing car would do for starters. A small model purchased for £4 was the starting point. The car will be ready for his third birthday so plenty of time (or so I thought). Continue reading
303 and 305 High-Capacity Positive Displacement Pumps
Updated Spring 2016
For measuring epoxy accurately, Gougeon Brothers, Inc. has introduced high-volume epoxy pumps that are extremely robust. These pumps dispense epoxy faster than any pump the company has previously offered. The 303 and 305 Positive Displacement Pumps work by trapping a fixed amount of resin and hardener, then forcing (displacing) that trapped volume into the discharge pipe or system. The mechanics of this setup mean that increases in resin viscosity due to temperature changes will not slow dispensing speeds. Positive latching lids help prevent contamination of resins and hardeners.
The new 303 Positive Displacement Pump is calibrated for WEST SYSTEM 3:1 ratio epoxies (105 Resin with 207 Special Clear Hardener or 209 Extra Slow Hardener) and is easily identified with a red base. The new 305 Positive Displacement Pump is calibrated for 5:1 ratio epoxies (105 Resin with 205 Fast Hardener or 206 Slow Hardener) and has a blue base.
Positive Displacement Pumps are also available with drum fittings. These connect directly to WEST SYSTEM Resin and Hardener drums so there is no need to decant materials. This setup conveniently streamlines the metering process for high-volume users, saving both time and money.
