For pumping any media applied in refrigeration industry:  ammonia,freon,silicone oil etc.

Hermetic Ammonia Pump - High-Quality, Factory-Direct & Customizable

Factory Overview

We are a professional China-based manufacturer specializing in hermetic ammonia pumps, with years of experience in serving global clients. As a direct factory, we eliminate middlemen to offer cost-effective prices (20%-30% lower than market average, MOQ 1 unit), implement strict quality control, and provide flexible customization to meet diverse industrial cooling needs.

Core Functions & Performance

Our hermetic ammonia pump is a key component for refrigeration systems, mainly used to transport ammonia refrigerant in industrial cooling, cold storage, and food processing refrigeration systems. It features a hermetic structure to prevent ammonia leakage, ensuring safe operation. With high efficiency, stable performance, and strong corrosion resistance, it can maintain stable refrigerant circulation, effectively supporting the normal operation of refrigeration systems.

Quality Assurance & Customization

All hermetic ammonia pumps comply with CE, ISO, and ROHS standards, undergoing strict pre-delivery testing to ensure reliable quality and long service life. We provide tailored customization, including pump flow rate, pressure, and size, to match your specific refrigeration system requirements. Professional after-sales support is provided for global clients.

Product Description

Hermetic refrigeration pump is a combination unit of centrifugal pump and 3-phase AC motor, with the hydraulic section connecting directly with the motor drive shafto constitute the rotor component jointly. The stator can is embedded on the inner side of the stator to isolate both the rotor chamber and stator chamber, that makes Hermetic pumps sealless completely. When the pump is operating, the axial force is balanced automatically and hydraulically.

The stator can is imported from Germany, that is formed by rolling in a special process to have a high precision, a good quality free from welding defects, that ensures sfitiently the canned motor pump to operate reliably and stably.

The slide bearing is in FH82A to have such advantages as high strength, good wear resistance, etc, and a service life 10 times more than resin impregnated graphite bearing.

Hermetic refrigeration pump consists of CNF series and CAM2 series, in which CNF series is in a horizontal single-stage structure and CAM2 in a horizontal muli-stage structure, and both are in the form of axial suction, radial discharge.

Application

Hermetic refrigeration pump is widely used in the refrigeration industry for safe delivery of such refrigerants as liquid ammonia (R717)， Freon (R22/R12), silicon oil, etc.
