The first thing you should do before installing the well or jet pump – is to measure the distance from the water to a level drain hose and make the necessary length.
Because of its high strength, light weight and resistance to moisture is best to use plastic PVC pipes with a diameter of 18-20 mm.
Hang the pump is on a nylon cord, load at break is five times greater than the weight of the jet pump.
Do not use for hanging metal cable or wire, since the vibrations caused by the jet pump, so the cable can break mounting lugs and the pump may fall into the well.
To suppress the vibration of the well jet pump (if the length of suspension is less than 10 meters) using spring-loaded suspension, which is attached to the end of the nylon cord. This suspension can be built from the medical or harness made of elastic rubber.
Mounted on the convertible jet pump can be lowered into the water, but so down to the bottom left at least 30 cm and the depth does not exceed the allowable rate for the shallow well jet pump. Make sure that the pump does not touch the walls of the well or put it on his body protective rubber ring.
From the jet pump, we can advise you on the brand Grundfos, which has established itself as a reliable, effective and proven company, which is based, is a superior quality of products. This includes greater attention to the constructive part of the design and selection of materials and manufacturing processes. A large amount of own production ensures high performance, healthy working environment and effective protection of the environment. Also in our catalog are jet pumps of domestic and US local brands (FloForce, Little Giant).
1. Plumbing valves, whether or gate valve wedge gate valves, awkward to install because of the large, compared to ball valves size and weight for height. Weight exceeds the weight of the valve ball valve by 1.5-2 times.
2. In the grease interceptor, due to a recurring cycle of “open-close” very quickly wear seal, he begins to flow. At an absolute grease trap seal closure, and as a consequence of the absence of leaks. This in turn increases the overall service life of steel grease interceptors.
3. Because of the low quality of water in municipal networks, grease traps are very easily damaged and the 20 gallon grease interceptor, which leads to the need to replace Plumbing valves on the new one. Steel ball valves have a long maintenance-free operation and maximum service intervals range, as seals are made of Teflon. PTFE seals are in contact with the buffed area have little or no wear. This node is a ball valve can withstand several thousand cycles, “open-closed”.
4. Due to water hammer in heating a gate on a regular basis is sticky gate overlap and thus involuntary trunk pipelines. Because of the design features of the ball valve, the situation with him is impossible.
5. Plumbing valves is not a full bore product, which creates additional resistance to flow of fluid in the systems of heat consumption. Coefficient of flow resistance is a ball valve (like a smooth straight pipe). A useful effect of a ball valve – no loss of pressure in the water system, which increases the overall efficiency of heating systems and water supply.
6. Backflow preventers on high pressure and tightening the dense packing, the loop ‘opening and closing “is difficult because of the small diameter of the flywheel. This in turn leads to the use of assistive devices to facilitate the rotation of the flywheel bolts. Also, for the full opening or closing the backflow preventer to perform several full turns the flywheel. Backflow preventer is easy to open, or closed by turning the rod 90 degrees. In this case it is possible to visually determine open or closed backflow preventer.
