What You Need to Know about Small Solenoid Pumps

syrup pumps

Besides syrup pumps, hydraulic pumps are the mechanical devices utilized in moving fluids. There are many types of pumps in general use. Some of them work at low speeds while others at higher speeds.

A solenoid pump is utilized in the water treatment process and chemical processing plants. That device is one of the simplest kinds of pumping equipment as it consists of a lesser number of components. It comprises a solenoid which is a helix of wire tired around an iron or a steel core. When an electric current passes through the coil, the core turns out to be a magnetic object because of the electromagnetic effect. Due to the magnetized core, the diaphragm comes back to its initial position.

Small solenoid pumps are based on the same principle and they are grouped in 3 series including:

  • Mono pumps
  • Syrup pumps
  • Duplex pumps

The pumps in the mono series are utilized in various applications where safety is important such as in:

  • Steam generators
  • Espresso coffee machines
  • Beverage vending machines
  • Carpet cleaners
  • Water carbonators
  • Spraying systems
  • Smoke generators
  • Water purifiers

This tool can pump a wide variety of fluids, for instance:

  • Low viscous syrups
  • Drinkable water, etc.

Syrup pumps series are designed for fluids with a viscosity of up to 400 CST while duplex ones operate on the oscillating piston principle and are designed for tasks such as:

  • Reverse osmosis
  • Ultrafiltration
  • Post-mix drink dispensers, etc.

Small gear pumps transfer the liquids by utilizing two rotating gears. It’s utilized in areas such as in:

  • Medical and surgical equipment
  • Laser apparatus
  • Laboratory instrumentation
  • Ink-jet printing systems
  • Cooling systems and sampling

They are popular for their compact design and great performance. Additionally, they can handle a selection of corrosive liquids keeping the safety feature intact. The housing of these pumps and internal materials are constructed using steel.

The fluids in some applications are very hard to handle. For that reason, it becomes difficult to decide the right working solutions. Nevertheless, with new models of liquid transfer machines, this daunting task has become easier.

They create no noise during their operation. They are free of pulsation and can transfer relatively high-level temperature liquids with a low coefficient of expansion. Also, the structure of this equipment involves an inner magnet that is connected to the driving gear and an outer magnet joined with a motor shaft.


Hopefully, you have learned something about syrup pumps and other types of solenoid pumps. Knowledge is power so when you know, you’re in a better position to make informed decisions.
