Rain Bird MPR-9SST side strip spray nozzle - rectangular pattern 2.7 x 5.5 m

Rain Bird MPR-9SST for rectangular lawn areas

The Rain Bird MPR-9SST is a specialised side strip spray nozzle designed for automatic irrigation of rectangular lawn areas. With a coverage pattern up to 2.7 m wide and 5.5 m long, it is particularly suitable for medium-width lawn strips alongside garden paths, patios, driveways and property boundaries. Its fixed rectangular spray pattern provides targeted irrigation for areas that are difficult to cover efficiently with conventional circular or semicircular spray nozzles.

The nozzle is installed at the midpoint of one of the long sides of the lawn strip. From this position, it distributes water to the left and right along the strip while covering its width. This allows an elongated lawn area to be irrigated from a side position without placing a sprinkler in the middle of the grass.

Rectangular spray coverage up to 2.7 x 5.5 m

The Rain Bird MPR-9SST produces a fixed rectangular side strip spray pattern. Depending on operating pressure, it covers an area measuring 2.7 x 4.6 to 2.7 x 5.5 m. The maximum coverage of 2.7 x 5.5 m is reached at 2.0 bar. Its 30° spray trajectory supports water distribution across the rectangular lawn area.

The integrated stainless steel adjustment screw allows the spray distance to be reduced. This helps you adapt the coverage to the dimensions of your lawn during installation. The rectangular spray pattern itself is fixed and cannot be changed to a different spray angle. For suitable coverage, position the nozzle at the midpoint of the long lawn edge and align the spray pattern with the length of the area.

Matched precipitation rates for garden irrigation

The MPR-9SST belongs to the Rain Bird MPR Series. MPR stands for Matched Precipitation Rate and refers to coordinated precipitation rates across different nozzle patterns. The series includes various circular spray angles and specialised strip patterns, allowing different lawn shapes to be incorporated into an automatic irrigation system. The MPR-9SST adds a wider and comparatively shorter side strip coverage pattern to the range.

Depending on operating pressure, the nozzle requires approximately 5.1 to 6.5 litres of water per minute. At 2.1 bar, the manufacturer specifies a water consumption of approximately 390 litres per hour. Consider this requirement when planning your irrigation zone. Available water pressure, flow capacity and correct sprinkler positioning are particularly important for reliable lawn irrigation.

Easy installation on Rain Bird spray bodies

The Rain Bird MPR-9SST fits compatible Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series. A suitable filter screen helps protect the nozzle from debris and supports consistent water distribution. The stainless steel adjustment screw allows the spray distance to be reduced during installation.

For particularly narrow and longer lawn strips, Rain Bird offers the MPR-15SST with a maximum coverage area of 1.2 x 9.2 m. Other strip nozzles, including the MPR-15CST, MPR-15EST, MPR-15LCS and MPR-15RCS, are designed for different sprinkler positions. This allows you to select a suitable model for the shape of your lawn and the intended installation location.

Frequently asked questions about the Rain Bird MPR-9SST

What area does the Rain Bird MPR-9SST cover?

Depending on operating pressure, the nozzle covers a rectangular area measuring 2.7 x 4.6 to 2.7 x 5.5 m. Maximum coverage is reached at 2.0 bar.

Where should the MPR-9SST be installed?

The side strip nozzle should be installed at the midpoint of one of the long sides of the rectangular lawn area. From there, it distributes water to the left and right along the strip and across its width.

Does the 5.5 m length refer to one direction?

No. The 5.5 m refers to the total length of the rectangular spray pattern. With the nozzle centrally positioned along the long edge, coverage extends approximately 2.75 m to the left and 2.75 m to the right.

How much water does the MPR-9SST use?

Depending on operating pressure, the flow rate ranges from approximately 5.1 to 6.5 l/min. At 2.1 bar, Rain Bird specifies approximately 390 litres per hour.

Can the rectangular spray pattern be adjusted?

The basic spray pattern is fixed. The spray distance can be reduced using the stainless steel adjustment screw, but the overall shape of the coverage pattern remains unchanged.

Which sprinkler bodies are compatible?

The MPR-9SST fits compatible Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series.

What is the difference between the MPR-9SST and MPR-15SST?

The MPR-9SST covers a wider, shorter rectangular area measuring up to 2.7 x 5.5 m. The MPR-15SST is designed for narrower and longer lawn strips, covering up to 1.2 x 9.2 m. Both nozzles are installed at the midpoint of a long side of the lawn area.
