Portable Sanitary Centrifugal Pump With Low Vibration Protection Motor

Portable Sanitary Centrifugal Pump With Low Vibration Protection Motor

Application

The GKH sanitary centrifugal pump is a kind of highly-efficient and economic centrifugal pump. In addition to meeting the requirements for sanitation and soft treatment to products, it also has chemical stability. The GKH sanitary centrifugal pump is widely used for conveying various liquid materials in such fields as dairy, beer, beverage, medicine, biological engineering, fine chemical industry, etc. It can be used to convey ordinary solutions of low and medium viscosity, and solutions containing suspension or corrosive solutions.

The form of the GOBOR sanitary centrifugal pump is single stage, single suction and open-type impeller. The pump shell and impeller are elaborately designed to reduce the resistance and thoroughly eliminate the dead corner of sanitation. Thanks to its unique structure, the flow speed of liquid in the pump is enhanced, so that the integral performance of the pump is improved. It is provided with excellent sanitary performance, so it is easy to be cleaned.

It can meet the requirements for sanitation and soft treatment to products and has the chemical corrosion resistance.

Motor

1. The motor is designed and manufactured according to international standards International Electrotechnical Commission IEC34, IEC72

British Standard BS4999-5000

Australian Standard ASI 359-2

German Standard DIN 42673

Conforming to"CE"mark requirements

2. The motor conforms to the following standards GB 755-87

GB10069-88

Q/JBQS 28-20003. Excellent electric performance Low noise, low vibration Protection grade of high performance The standard protection grade of the motor is designed as lp54, IP55

According to user requirements, higher protection grade can be offered.

Suitable for use with double frequency and wide voltage.

Features

The prominence of GOBOR pumps relies on many factors. The high performances and energy-saving performance of our pumps originate from the inside geometrical features, so that the excellent fluid features and simple CIP are ensured, and the requirements for no-fault operation and low maintenance are guaranteed with the solid pump structure.

In addition, the GOBOR pump avoids disadvantages in all design details, such as the precise balancing design, installation of the booster, and outside spring of the shaft seal(without using the inside spring).

Among the GOBOR pumps, most sanitary centrifugal pumps use the same mechanical seal, which simplifies installation and warehousing of spare parts. The GOBOR pump products have the same modular features, which simplifies maintenance, modification and seal change.

Standard design

The GKH sanitary centrifugal pump is composed of motor, pump shaft, mechanical clamping jacket, sanitary mechanical seal, connection support, rear plate cover, impeller, pump shell, etc. The GKH sanitary centrifugal pump has large internal round chamfer and cleaning type seal. The GKH sanitary centrifugal pump speciallydesigned for CIP has the stainless steel protection cover used for protecting the motor, and the equipment is supported by four adjustable feet.

Shaft seal

The GKH sanitary centrifugal pump is provided with a set of externally mounted single end mechanical seal or water injection mechanical seal. The static ring of the mechanical seal is made ofstainless seal, silicon carbide or tungsten alloy. The dynamic ring is made of stainless seal, carbon, graphite or tungsten alloy. The seal ring of the water injection type seal is a durable lip seal. The series of pump products can also be equipped with the double end mechanical seal.
