Sprinklers irrigation

Reality today may differ slightly from what is shown in the picture.

Спринклеры серии 900 - 940

Model 900-940 is a two-jet sprinkler. It has a stable, balanced position during operation, does not swing, rotates very evenly, moistening the ground, and has a relatively low water consumption. The sprinkler closes after completion of work, which prevents insects from entering. This model is ideal for low volume systems, vegetables, flowers, seedling nurseries, landscaping, home gardens, refrigeration, and frost protection systems.

Low-volume irrigation systems are used to irrigate large areas of open ground. Sprinklers model 900-940 with an irrigation radius of 8-12 meters are the most popular and budgetary for farms. They have a low water consumption, a large drop that allows irrigation of a given radius, are simple and easy to install, have high reliability and an affordable price. We recommend these particular models for sprinkler irrigation for irrigation of vegetable and potato fields, industrial crops, pastures.

Sprinklers are available in three varieties, which differ mainly in the type of attachment for installation on the field and in the way of water connection.

Model 900 the simplest available.
Model 920 is installed on a metal rod (stand) and is connected with a thin hose to the distribution pipe.
Model 940 has a 1/2 or 3/4 inch threaded nut in the bottom for connection to the water supply pipe.

The Model 900-900-940 Sprinklers are designed for large areas. They can be used both separately installed and continuous irrigation, that is, according to a special scheme on large areas for irrigating vegetables, industrial and forage crops, flowers, lawns, for landscape design, for seedlings, nurseries, greenhouses, etc. The sprinkler creates two jets of water that cover a circle up to 15 meters in diameter. The jets rotate slowly and irrigate the irrigated area evenly. The design is well balanced and the sprinkler runs smoothly and without vibration. The sprinklers are equipped with a unique built-in filter and close when the water supply is cut off to prevent insects from entering.

These sprinklers are very promising for frost protection systems and, with an irrigation rate in terms of rainfall of 2 mm / h, provide maximum protection with minimum water consumption. Sprinklers can be installed at a height of 20 to 100 cm above the soil surface. The optimal working pressure is 2.0-2.5 atm. In large areas, pressure regulators installed at the inlet to the sprinkler can be used to equalize the pressure and flow rates at the beginning and end of the lines. This allows for perfect irrigation uniformity. The optimal arrangement for installing sprinklers on the field is 10x10 meters. This scheme allows you to guarantee uniform moisture over the irrigated area.
