Guzzler Pumps for Maple Sap Collection and Processing

Bosworth’s Guzzler diaphragm pumps are widely used to establish vacuum on maple sap collection lines. Unlike expensive vacuum pumps that require a releaser to isolate sap from the pump, Guzzler diaphragm pumps can both establish the vacuum and transfer the sap through the pump. Guzzler vacuum pumps are available with 115VAC and 24VDC motors. The Guzzler pumps are rated at 22 in of Hg vacuum. Our single diaphragm pumps (the "GE-" pumps) can support vacuum on up to 400 taps; the double diaphragm pumps (the "G2-" pumps) are rated at vacuum production on up to 800-900 taps. Guzzler pumps are available in standard gray Acetal plastic, as well as in the white (pigment-free) Natural Delrin. The wetted components of these pumps are made of FDA-approved materials for any component that comes in contact with the sap.

Additionally, Guzzler hand pumps are used to transfer syrup through maple syrup presses. Both the GH-0400N and the recently introduced GH-0500N pumps are made of FDA-approved materials for all components in contact with the syrup.

SapCheck - New this Year!

SapCheck is a new product for remote monitoring and control of your Guzzler pump at your sugarbush. SapCheck comes with a temperature sensor, vacuum sensor and a tank float switch. You communicate with SapCheck using simple text messages to receive current temperature and vacuum readings at your sugarbush. SapCheck will send you a text message to alert you in real-time to a loss of vacuum or that your sap collection tank is nearly full. You can have SapCheck automatically turn your pump on/off based on temperature at the sugarbush. And you can remotely control your pump to turn it on/off at any time. SapCheck does not require an Internet connection; as long as you have the ability to send/received text messages at your sugarbush, you can use SapCheck. SapCheck is designed and priced to be affordable for smaller sugarbushes.
