Walla Walla MP Rotator sprinkler

MP Rotator Nozzles

Primary Application

The MP rotator provides the crucial ability to water small areas normally covered by pop-up spray heads, and to do this at a precipitation rate that is matched to typical rotor sprinklers. It is normally an extremely poor design practice to install pop-up spray sprinklers on the same station as rotor sprinklers due to the widely different precipitation rates between spray and rotor sprinklers. The MP Rotator has, however, been specifically designed with this application in mind. By matching the precipitation rate of typical rotors, the MP Rotator has made it practical to add those small problem areas that are tough to cover with rotors, yet keep those sprinklers on the same station as your rotors. In many cases this can save long runs of pipe or dedicated stations which result from small odd-shaped areas in the landscape located near large areas being irrigated by rotors. Sometimes, the use of only one or two of these MP Rotator nozzles can eliminate an additional station, resulting in savings on valves and allowing the use of smaller controllers.

In the 8-30' (2.5-9m) range, the MP Rotator® sprinkler is the intelligent choice for irrigation because it offers design, performance and cost advantages over sprays and single-stream, short-range rotors. The high-uniformity, low-application rate MP Rotator is also the most efficient, water-saving sprinkler in its class. The MP1000, MP2000, and MP3000 can be combined on the same station because they all maintain matched precipitation, even after arc and radius adjustment. This provides a new level of design and installation flexibility for turf and landscape irrigation.

Features and Benefits Walla Walla MP Rotator sprinkler

Radius Choices

  • MP1000 Rotator: 8-15' (2.5-4.6 meter)
  • MP2000 Rotator: 13-21' (4-6.4 meter)
  • MP3000 Rotator: 22-30' (6.7-9 meter)
  • These ranges include the 25% radius reduction capability. To achieve maximum radius reduction with any MP Rotator model the pressure at the sprinkler head must be regulated to 30 PSI (2 BAR).

A Water Conservation Tool

  • Multi-trajectory rotating streams provide unmatched uniformity
  • Automatic matched precipitation even after arc and radius adjustment
  • Low application rate reduces runoff on slopes and tight soils

MPR Nozzle Flow Data

For optimum efficiency if you use other conventional rotors, such as PGPs, I20s or I40s you should you should size your other rotor nozzles to match the precipitation rates in the table below, typically between 0.40 and 0.45 inches per hour.
