West System 300 Mini Pumps Epoxy Metering Pump Set (3-Pack)

These 300 Mini Pumps from West System are designed for convenient and accurate metering of Group A, B, and C resin-based epoxy. This 300 Mini Pump Set contains one 105 Epoxy Resin Pump, one 205/206 Epoxy Hardener Pump, and one 207/209 Epoxy Hardener Pump. Pumps mount directly on the resin and hardener containers and eliminate the mess involved with measuring by weight or volume.

Calibrated for Precision

These pumps are calibrated to deliver the proper working ratio with one full pump stroke of resin for each one full pump stroke of hardener. 105/205-206 pumps deliver approximate 0.8 fl oz of resin/hardener with one full stroke of each pump. 105/207-209 pumps deliver approximately 0.9 fl oz of resin/hardener with one full stroke of each pump.

For Group A, B, and C Containers

Made of durable polypropylene, the Mini Pumps gives years of dependable service. As packaged, the pumps are ready to install on the Group Size B containers. A package of extension tubes for Group Size A containers is included with this pump set. Group Size C extension tubes are included with the 105-C Resin and 207-SC or 209-SC Hardener containers.

Accurate Metering

West System Epoxy Metering Pumps are calibrated for accurate metering of West System Epoxy Resin and Hardener at the proper mix ratio, while eliminating mess and guesswork. The correct epoxy resin to hardener ratio is important to ensure that the epoxy reaches its full potential for cured physical properties.

Ratio Verification

The ratio of each pair of Mini Pumps is controlled by the installation of a clip, that limits the stroke (and volume) of one or both of the pumps. All Mini Pumps are carefully inspected during this operation and during packaging. But the final test of a pump’s performance can’t be made until it is actually pumping resin or hardener. The ratio verification test described in the instructions confirms that both pumps are dispensing the correct volume and that the ratio of resin to hardener is within a critical narrow range.

Why Use Epoxy Metering Pumps?

Epoxy metering pumps ensure you’re using the correct ratio of resin to hardener, crucial to epoxy performance. Depending on the hardener you select, West System Epoxy is mixed at a ratio of five parts resin to one part hardener, or three parts resin to one part hardener. At the proper mix ratio, the number of chemically reactive sites in the resin balances the number of reactive sites in the hardener. The resin molecules are larger than the hardener molecules, and have few reactive sites, hence the 5:1 or 3:1 ratio. When the mix is stirred thoroughly, the resin and hardener molecules react to develop full strength.

Epoxy Metering Pumps for Fast Dispensing

West System Pumps dispense epoxy faster than any pump they’ve ever offered. These pumps work by trapping a fixed amount of resin and hardener then forcing (displacing) that trapped volume into the discharge tube. These offers improved epoxy pumping performance because changes in viscosity due to temperature change do not affect their performance.
