Internal Gear Pumps Jacketed Internal Gear Pumps

Editor: Ahlam Rais

Envirogear has announced that its G Series Internal Gear Pumps are now available with jacketing. Specifically designed to enhance the G Series Pump’s temperature control and stability, these new jacketed pumps are perfectly suited to handle a variety of challenging applications such as carbolic acid, liquid sulfur, roofing manufacturing, general chemicals, bitumen, paint, chocolate, molasses, waxes and heavy fuel oil.

The Series’ jacketing system efficiently heats the seal area and pump internals to maintain process temperature and integrity during operation. This ensures high-freeze point liquids remain in a fluid state when processed through a G Series pump. The jacket also provides faster pump startup and reliability when compared to a cold pump, states the company.

The new jacketed pumps not only expand the current application range of the Series pumps, but they also provide a tremendous benefit to manufacturers who prefer to utilize one brand of pump across their entire operation, adds the firm. These manufacturers no longer have to mix and match pump brands based on the application. They now have the option to outfit their entire facility with both non-jacketed and jacketed G Series Pumps from Envirogear, mentions the company.

The new jacketed pumps are available in cast iron configurations and in sizes G2-55, G2-69, G2-82, G2-133 and G2-222. The pumps come standard with a jacketed bracket to provide temperature control in the bushing area that radiates to the low-velocity area behind the rotor, a typical cold spot in the pump. Additionally, each pump configuration is available with a jacketed head and relief valve. The G2-55 and G2-133 also have the option for a jacketed case.

Jacketed G Series Pumps introduce temperature control to Envirogear’s already successful heavy-duty pump line. They expand on the established tradition of interchangeability with up to 95 % of mechanically sealed, packed and seal-less internal gear pumps currently on the market. New jacketed parts are standardized to ensure competitor interchangeability while the oversized bearing housing and seal chamber allow for seal replacement without pump downtime, concludes the firm.
