Sinker Bars are heavy solid steel rods with standard rod threads on both ends. They are run as part of the rod string and located immediately above the pump. The advantages of sinker bars in a steel rod string are the elimination of compression in lower rod sections and the proper operation of the pump valves. The use of sinker bars is an absolute necessity because of the low weight of fiberglass rods. Sinker bars are used with strings of sucker rod that are not rigid or that are lighter than 43 lbs per 100 foot of rod. These sinker bars when connected to the working plunger assembly in the cylinder increases pumping capacity by up to 30% by keeping tension on the string of rod and help insure the full stroke of the cylinder. These sinker bars are painted to resist corrosion.
Sintered air diffuser stone is extremely durable and washable (reusable) air diffusing media. It is made from fused alumina under ultra high temperature and pressure. This stone is applicable in acidic or alkaline waters. It is an ozone resistant stone. It is suitable for aquarium, pond, fish hatchery and aquaculture applications.
Muffler is a device for reducing the amount of noise emitted by a machine such as an internal combustion engine or a gun. Sintered bronze mufflers are produced by heating the bronze material below its melting point until its particles adhere to each other. Sintered bronze muffler provides superior mechanical strength for any industrial environment. They are highly resistant to various chemicals and solvents, capable of high temperatures and easy to clean with various industrial cleaners and de-greasers.
