Accessories
502 pumps can be equipped with a maximum of two pump elements. A seal is always included.
When installing additional pump elements, please follow installation instructions 951-171-009-EN. Pump elements can also be removed. Any unused opening must be sealed with a plug. Each pump element must be protected with a safety valve. Nickel-plated pump elements are used in corrosive environments, such as the food industry. The B7 DN pump element is suitable for problematic greases that are harder than standard greases.
