D Type Electromagnetic Solenoid Dosing Pump

Solenoid-driven metering Pump is the perfect solution for small capacity need. It is equipped with LCD display, easy to adjust the fluid delivery proportion.

ND Type Mechanical Motor Dosing Pump

Motor driven dosing metering pump are much more powerful and stable, Spring Return Mechanical Diaphragm Pump are widely used in waste water treatment, chenmical, food and industries.

ND Electric Stroke Adjuster

As for ND electric stroke adjuster, Newdose can provide you with two types of dosing pumps including remote control electric stroke adjuster and manual control electric stroke adjuster. The adjuster receives an analog signal (4-20mA) and can accurately modify the displacement of the dosing pump.

Dosing Pump Faqs

The value of the safety valve should be in the range of the working pressure of the pump, cannot adjust the pressure higher than the max pressure of the pump. If the max working pressure of the pump is 3 Bar, the safety valve should be set as 3 Bar, or lower than 3 Bar. Over-pressure is one of the reasons that cause the broken of the pump.

The float switch is a very important device to control the liquid level of the tank. The float switch can automatically control the start and stop of the pump according to the variation of required liquid level, with no need of a special person to care about, making operation quite easy.

When the level is lowered, the float sinks, and the contact point inside the switch is closed. This contact point can be used to control the metering pump. For example, it can stop the metering pump 1 and start the metering pump 2. On the other hand, it also can indicate that the cartridge is empty by turning on the alarm/indicator light. And the float switch can be applied to the tank to indicate that the tank is full and to stop the metering pump.

NEWDOSE pump has two types, solenoid driven and motor-driven dosing metering pump, the capacity range is 1~6000Lph.

For solenoid dosing pump, there are filter, sprayer, connectors, and pipes in the accessory kit.

The motor-driven pumps don’t be equipped with any accessories. It has to choose the other parts according to the installation situation.

  • Confirm the flow rate of the solution (how much liters of the solution should be transferred in one hour?) 
  • Check the main characteristics of the solution, such as corrosivity, viscosity, concentration, and temperature.
  • Confirm the pressure of the dosing system.
  • Confirm the suction height.
  • Check if the dosing system needs any signal control, such as pulse signal, 4-20mA signal, or RS485.

To select one proper size of pulsation damper could decrease at least 90% pulse, which makes the liquid flow more stable. Equipped with pulsation damper can help to slow down the accelerated speed of the flow and protect the pump head.

  • Do not make the pressure value higher than the max working pressure of the pump can hold.
  • When there is pressure in the suction point, adjust the pressure of the injection point is 1bar higher than the suction point.
