Technical data

The Metso XR and XM series pumps has a primary high-performance hydro-dynamic expeller which effectively seals the gland dry when the pump is running. A secondary grease lubricated packed gland seal prevents leakage when the pump is not running.

Flushed gland seals are available which can be supplied as either a “full flow” or “low flow” gland seal. Various options of mechanical seals are available upon request. The materials used in the “wet end” are dependent on the application. The options are the very best available, providing excellent wear properties and corrosion resistance. The standard impeller material is a High Chrome white iron alloy with a nominal hardness of 600 BHN. The standard rubber liner material is a high-performance natural rubber. Other material options are available upon request.
