Guzzler diaphragm pumps are widely used as priming pumps on fire safety equipment. Guzzler hand pumps can run dry without any damage to the pump. They have a lift capacity of 12 feet without a check valve, and up to 22 feet with a check valve.
Durability has been engineered into the Guzzler product line. Guzzler pumps are made out of durable, lightweight Delrin plastic, but are also available in rugged, epoxy-coated aluminum. Guzzler Delrin pumps can be equipped with epoxy-coated aluminum clamp rings for added durability. Clamp ring options include an aluminum clamp ring with stop brackets that prevents pump over-stroking during vigorous use.
Guzzler pumps are available to work with hose sizes from 3/4 inch up to 2 inches.
