For medium head applications, the Dyna-Glas Pool Pumps are so convenient, reliable and quiet, they often go unnoticed! With its "see thru" lid, the large-capacity trap provides superior convenience in keeping debris out of your pool. The impeller/diffuser design enables the Dyna-Glas to quietly move a lot of water while consuming very little energy, while the specially designed base helps keep the operation quiet. The pump itself easily lifts in and off if service is required. The finger opening drain plugs let you winterize your pump without using tools.
