ONE OF THE biggest challenges for customers wishing to replace a pump seal is correctly identifying which seal they actually need.
MORE PICS of another Gold Coast City Council pump converted to cartridge mechanical seals.
Gland Packing vs Cartridge Mechanical Seal
An end face cartridge mechanical seal, also referred to as a mechanical face seal but typically simply as a mechanical seal, is a kind of seal made use of in rotating devices, such as pumps, mixers, blowers, and compressors. Earlier pump designs made use of mechanical packing (otherwise understood as Gland Packing) to seal the shaft.
GOLD COAST City Council chose Anthony Butler of Select Seals to convert all their pumps from using gland packing to now run using cartridge mechanical seals.
This Warman Pump has now been running more efficiently and reliably for 4 years.
SELECT SEALS’ cartridge seal repair facility is one-of-a kind. We have made a commitment to repair all mechanical cartridge seal styles, regardless of manufacturer.
We repair to like-new condition. If the cartridge seal is not repairable, we will quote a new cartridge seal as a replacement or offer a range of exchange programs to suit the customer’s needs.
THIS SOUTHERN Cross Vertical Pump was recently converted from gland packing to a cartridge mechanical seal.
Our Engineering Department specially designed and manufactured a custom cartridge mechanical seal for this specific application.
IN MECHANICAL seals main friction happens in the axial direction, between faces (seal rings) lapped to a high precision. Wear is compensated in axial direction by springs or bellows.
Many mechanical seals do not wear shaft at all. Contact pressure and thus the friction force is kept to a minimum by a balanced design.
