But they also find wide use in other municipal applications, such as storm water pumping and irrigation. Additional areas of importance include industrial applications and manure handling in agriculture… Other application areas include raw-water handling, aqua-culture, and irrigation.”

MONOPOLY PRICING

Some OEMs can enjoy a monopoly on spare parts due to unusual design. Replacement seals are priced at a strong premium for a plastic-bodied spring seal.

Excessive seal prices force Repair Shops to attempt seal repairs, and some even have OEM seals custom-machined from scratch.

e.g., All type 06 metallic seal parts are manufactured in Stainless Steel

NO PLASTIC !!!
