Figure 1. Assembling Your Pump Your Guzzler G2-0501N pump ships with the inlet and outlet mani- folds disconnected from the pump and packed separately in the box. To assemble your pump, simply attach each manifold to either side...
Figure 5 Pump Setup Figure 5 shows a recommended installation setup for the Guzzler G2-0501N pump when used for vacuum produc- tion on a maple sap collection line. The topics below refer to that figure in more detail. Protect the Pump from the Elements However you deploy your pump, ensure it is protected from the elements and securely mounted.
Pump Setup / Tips for Best Operation Recirculation Line for Best Vacuum Guzzler pump valves seal best when wet. To achieve the best vacuum with your Guzzler, we recommend that you install a small (1/8” to 1/4” in diameter) recirculation line from your collection tank back to the inlet of the Guzzler (Figure 5).
Maintenance - Changing a Diaphragm Maintenance - Changing a Diaphragm Over time, the elastomer components of the pump (i.e., the diaphragm and valves) will fail. If a diaphragm fails, the pump may continue to develop some vacuum (depending on the size of the hole/tear), but it will be significantly re- duced, and you will see sap leaking from the diaphragm and out through the “weep”...
Maintenance - Changing a Diaphragm / Changing Pump Valves Installing a Diaphragm 1. Place the new diaphragm onto the base of the plastic clevis, ensuring it is seated on the raised central boss; install the button (rounded-edge toward diaphragm) and stainless steel washer.
Maintenance - Changing Pump Valves / Troubleshooting Removing the Valves—continued Remove the umbrella valve with a pair of pliers, pulling the flat of the valve until the stem is pulled through the valve stop center retaining hole (Figure 12). Inspect the valve for any tears. Inspect the valve pores and remove any dirt or material that may have become lodged in the pores.
