Metering pump Mixer
Application Guide

Dosing pump mixer MixRite actuated by the flow of water in the line on which it is mounted, with minimum loss of pressure. Water Water actuates actuator coupled to the proportional metering device. To operate the pump no external power source is required.

Dispenser sucks liquid additives in direct proportional relation to the amount of water flowing through a pump and mixes them with the water flowing in the irrigation system.




Action Water Drive:

Water actuator consists of a cylinder in which the piston moves. The piston has a valve system that allows you to control the fluid flow. The differential pressure on the piston and valve position change leads to a change in the direction of the cyclic movement of the piston.

Suction and dosing unit model 2502, 2504, 2505, 2510, 12502, 12504, 12505, 12510:

The suction and dispensing device comprises a piston connected to a water driven, resulting in its movement. The piston moves in the cylinder with the check valve. Movement of the piston under the influence of water leads to the desired absorption liquid additive from a container through a flexible tube. Sucked fluid is mixed with the main stream flowing through the pump.

In models 2512, 2514, 12512, 12514 liquid additive is injected via the bypass tube directly into the main line, bypassing the water drive.

Models 2502, 2504, 2510, 12502, 12504, 12510 has a ratio between the adjustment mechanism and the additive amount of water flowing through the pump .

Models 2500 2501, 2505, 12500, 12501, 12505 ratio of flowing water and the amount of additives is fixed and set at the factory and can not be changed.

Models 2512 IN , 2514 IN , 12512 IN , 12514 IN required additive through the bypass pipe and valve is injected directly into the water line, avoiding contact with the water drive.


MixRite operates in the following modes:

  • From a minimum flow of 20 l / h up to a maximum of 2,500 L / H
  • Low 4 ° C or above 40 ° C
  • The water pressure from 0.2 Bar to 6 Bar

Additives may be mixed with the flowing water in the following proportions by percentage:

  • From 0.2% to 2% in the models: 2502,12502,2512,12512,2512 IN, IN 12512
  • From 0.4% to 4% in the models: 2504,12504,2514,12514, IN 2514, IN 12514
  • From 3% to 10% in the models: 2510.12510
  • A fixed dose of 0.2% in the models: 125NO, 2500, 12500
  • A fixed dose of 0.8% in the models: 2501, 12501
  • A fixed dose of 5% in the models: 2505, 12505

Pressure reduction:

  • The pressure loss at low values of 0.1 Bar flow at high flow rates of up to 1 Bar
  • Models 0.2% -2%: from 0.1 Bar up to 1 Bar in proportion to the flow of water
  • Models of 0.4% -4%: from 0.2 Bar up to 1.2 Bar in proportion to the flow of water
  • Model 3% -10%, from 0.5 Bar to 1.8 in proportion to the water flow
