Hydrazine dosing unit
Hydrazine dosing unit

Hydrazine dosing unit

Equipment for water-chemical treatment, which is critical in the steam-water cycle of thermal power plants, industrial boilers, etc. Adding microdoses of hydrazine solution to the boiler feedwater reacts chemically with the dissolved oxygen (O₂) in the feedwater to form nitrogen and water.

Dosing unit for injection of ammonia into feed water

Dosing unit for injection of ammonia into feed water

Equipment for water-chemical treatment, which is critical in the steam-water cycle of thermal power plants, industrial boilers, etc. Adding microdoses of ammonia water (NH₂OH) or liquid ammonia (NH₃) to the boiler feed water to increase the pH of the feed water (usually maintained in the range of 8.8–9.3 or depending on specific conditions) allows the formation of a stable protective film of magnetite (Fe₃O₄) on the surface of the metal (for example, carbon steel).

Simple dosing block-modular unit

Simple dosing block-modular unit

The simple modular dosing unit is a complete plug-and-play dosing device. It is designed, manufactured, assembled and tested at the manufacturing plant in accordance with the customer's technological requirements, and then completely delivered to the site.

Dosing device for waste and sewage water treatment

Dosing device for waste and sewage water treatment

The dosing device, specifically designed for wastewater and sewage treatment, is a critical component of the “accurate dosing and mixing of reagents” in the entire water treatment system. It automatically dispenses specific chemicals into wastewater to achieve physical, chemical or biological treatment goals.

DZ-ZR190

DZ-ZR190

Thanks to the reciprocating movement of the plunger, the working medium is directly sucked in or pumped out. Since the plunger and seal are in direct contact with the fluid, the correct choice of plunger material and seal type will ensure more ideal pump performance during operation.

DZ-X80

DZ-X80

Thanks to the reciprocating movement of the plunger, the working medium is directly sucked in or pumped out. Since the plunger and seal are in direct contact with the fluid, the correct choice of plunger material and seal type will ensure more ideal pump performance during operation.

DZ-D2-1400

DZ-D2-1400

Thanks to the reciprocating movement of the plunger, the working medium is directly sucked in or pumped out. Since the plunger and seal are in direct contact with the fluid, the correct choice of plunger material and seal type ensures more ideal pump performance during operation.

ZFT Series PTFE Self-Priming Magnetic Pumps

ZFT Series PTFE Self-Priming Magnetic Pumps

Self-priming magnetic pumps of the ZFT series fully combine the advantages of a magnetic pump and a self-priming pump: they have a self-priming function, but at the same time they do not have a shaft seal, they use transmission through a magnetic coupling, which completely eliminates the phenomenon of drip leaks.
