How to Select Refrigerant Pump – Freon, Booster & Transfer Pumps Guide

When selecting the right miniature pump, it is essential to first understand the technical parameters of various pump types. The comparison chart below provides a clear overview of the advantages and disadvantages of different miniature pump technologies across key performance indicators.

In terms of performance, service life, and cost — the three factors most commonly evaluated by users — gear pumps offer the best overall value. A well-engineered Suofu NP Series micro magnetic gear pump delivers high pressure, strong stability, pulsation-free flow, excellent wear and corrosion resistance, strong self-priming capability, extended dry-running capacity, and an exceptionally long service life.

So, what is the quotation, price, or estimated cost for a Suofu NP Series micro magnetic gear pump suitable for refrigerant, Freon, booster, transfer, pressure, or miniature water pump applications?

When requesting a quotation, it is critical to provide the supplier with accurate operating condition details:

1. Pressure – inlet and outlet pressure requirements

2. Media – type, viscosity, pH level, corrosiveness, particulate content

3. Flow rate – required operating flow range

4. Ambient temperature – maximum and minimum temperatures

5. Port connection – thread size and type

6. Motor – applicable voltage, power, and speed

With these detailed parameters, the next steps of selection and pricing can proceed.

Step 1: Select the specific series and model based on flow rate requirements

Suofu NP Series refrigerant, Freon, booster, transfer, and pressure pumps offer different flow rate ranges across various series and models. Selection should be based on the required operating flow.

Step 2: Select internal core components based on media and operating temperature

As shown in the illustration, the internal core components of Suofu NP Series refrigerant, Freon, booster, transfer, and pressure pumps are available in multiple material options.

When placing an inquiry, it is essential to provide the operating conditions and fluid media details to ensure appropriate material selection. Some liquids contain corrosive agents or particulates that can damage internal pump components and shorten service life.

NP Series available materials:

Pump body / Clamp plate / Magnetic can:  SS316 stainless steel / Hastelloy / Specialty plastics 

Bearings / Gears: PEEK engineering plastic with special fillers

Shaft: Industrial zirconia ceramic

Magnetic drive: PPS-overmolded rare earth magnet

Seal ring: FKM / EPDM / PTFE / FVMQ / CR

Within the same series, different material configurations will affect the final price. Similarly, for the same material configuration, larger series models are priced higher than smaller ones.

Step 3: Select the appropriate motor based on voltage, power, speed, and control method

Suofu NP Series refrigerant, Freon, booster, transfer, and pressure pumps are compatible with a wide range of motor specifications. When requesting a quotation, customers may choose either Suofu's custom-matched motors or specify/self-provide motors of their own. Naturally, different motor options will affect the final pricing.

Once the model, internal component materials, port thread size, and motor configuration have been determined, a formal quotation for the Suofu NP Series refrigerant, Freon, booster, transfer, or pressure pump can be provided.
