ZF self-priming pump is a new generation of high suction range self-priming chemical centrifugal pump exclusively developed by our company. Through structural improvements, this equipment significantly enhances product performance while effectively extending its service life, and has obtained national patents(Patent number: ZL.7 ZL.4)The introduction of ZF self-priming pumps will become one of the most competitive products in the current market due to their high cost-effectiveness, making them an ideal replacement for single-stage single suction centrifugal pumps, submersible pumps, and submersible pumps. The materials are reinforced polypropylene (RPP) and polyvinylidene fluoride (PVDF).

Enhanced non-polar polypropylene, non-toxic, resistant to general acids, bases, and salts, with a working temperature range of -12 ℃ -80 ℃

Polyvinylidene fluoride (PVDF) has good airtightness, is non-toxic, non-polar, has good oxidation resistance, good mechanical properties, and is resistant to strong oxidants, halogens, and aromatic solvents. Its working temperature ranges from -40 ℃ to 135 ℃ (with solvent based media, it is recommended to use PVDF)

(It is strongly recommended to use a self-priming pump instead of a regular centrifugal pump to transport the medium, in order to avoid unexpected liquid interruption and production losses.)

Frequently changing accessories? Use ZF self-priming pump!

Can't detect it within 5 seconds of fluid interruption? Use ZF self-priming pump!!

The pump broke down inexplicably? Use ZF self-priming pump!!!

Unfortunately, not all media can be used with ZF self-priming pumps!!!!

ZF series self-priming pump disassembly diagram

Main material: Reinforced polypropylene or polyvinylidene fluoride

Mechanical seal: patented mechanical seal, double-sided silicon carbide.If used under alkaline conditions, please let us know and we will select a non press seal (patented structure) for you

Motor: Ordinary motor or explosion-proof motor.

One way valve: ordinary nitrile rubber or fluororubber

1、 The whole machine has only one sealing surface, with few leakage points and a high self-priming height.

2、 Depending on the temperature of the medium, running idle for 15-30 minutes without liquid interruption will not damage the equipment.

3、 Without embedded components, the pump will not fail as a whole due to corrosion of the embedded components.

4、 Patent machine seal, cooling surface is 3-6 times that of conventional machine seal.

5、 The most expensive accessory - pump casing, will never be replaced unless it is damaged by external forces or the medium is not suitable.

What you should know is different

Since the proposal of "making equipment with lower usage costs", the ZF series self-priming pump is one of the most successful products that has implemented this idea from the design stage.

Almost all self-priming pumps in the market will encounter this problem:

1. Too many sealing surfaces. New equipment is better, while old equipment is prone to sealing surface leakage, damage to equipment, and pollution; It will leak all the liquid inside the pump body; The leaked liquid will corrode the embedded parts in the pump body and directly damage the equipment. This is a big problem.The ZF pump has only one sealing surface and no embedded parts inside the pump body. There are fewer sealing surfaces, fewer leakage points, and it is also easy to locate. Even if there is a leak, it will not damage the equipment. High self-priming height.

2. Machine seal issue. Pumps all have a mechanical seal issue. In addition to normal wear and tear of the machine seal, many times it is abnormal damage, resulting in greater losses. We use a patented machine seal with a cooling surface 3-6 times that of a conventional WB2 machine seal, and the cooling surface extends into the interior of the pump body to prevent the formation of bubbles and avoid abnormal damage as much as possible.

In summary, the normal service life of ZF self-priming pumps is much longer than that of similar equipment in the market; The cost of replacing accessories is much lower than that of similar products in the market.
