Project Description
- Ideal for use in process pump
standardization - O-ring is dynamically loaded to prevent
shaft damage. - Dimensional modification of the stuffing
box chamber is not required due to
short radial installation height - Ideal to convert and retrofit pumps with
packings and large volume OEM
production - Cartridge unit factory assembled for
easy installation, which reduces down-
time - Rugged design for long operating life
- Foodstuffs and animal feed industries
- Sweet cider pressing and beverage production
- Viticulture and wineries
- Spirit production and alcohol industry
- Breweries and malt houses
- Sugar industry
- Pharmaceuticals and cosmetics industry
- Oil and gas industry
- Pulp and paper production
- Paint and lacquer industry
- Chemicals industry
- Automobile industry
- Water and waste water industry
