RP type stainless steel rotary pump

Product Introduction

30 years of craftsmanship in Zhongcheng Pump IndustryCorrosion resistant rotary pump、RP series stainless steel rotary pump( http://www.pumpzc .. Com/zzb-rp-2/) Industry! Produce corrosion-resistant rotary pumps and RP series stainless steel rotary pumps using * technology. Selection and quotation consultation. The principle of RP series stainless steel rotor pump is similar to that of gear pump. It is a positive displacement pump with two cam rotors of the same shape meshing and rotating with each other. During the rotation process, the two rotors form a vacuum chamber, which sucks in materials and discharges them at the outlet. According to the rotor shape of RP series stainless steel rotary pumps, they are also known as cam pumps, three bladed pumps, etc. The components that come into contact with the conveying material of the rotary pump are made of hygienic materials such as 304/316 stainless steel, and the seals are made of fluorinerubberMade of non-toxic materials, the pump chamber has no dead spots or non-metallic parts, suitable for CIP cleaning and steam disinfection, and meets the requirements of the US FDA and GMP standards.

Corrosion resistant rotor pump and RP series stainless steel rotor pump are especially suitable for conveying media that are easy to produce foam, high viscosity, concentration and any particles. The materials conveyed by them remain unchanged in original quality, without shear, and without any physical and chemical reaction. If external dynamic or static ring mechanical seals are used, they can be directly rinsed with water.

Corrosion resistant rotary pumps and RP series stainless steel rotary pumps are resistant to high pressure, not easily worn, and have no leaks. Small size, high flow rate, high head and pressure, suitable for long-distance and high resistance quantitative transportation.

The rotor and transmission gear of corrosion-resistant rotary pumps and RP series stainless steel rotary pumps are separated, and a certain gap is maintained between the various components in the pump chamber, without contact, wear, low noise, good reliability, long service life, and energy saving and consumption reduction. After configuring the frequency converter, the flow can be adjusted freely and used as a general metering pump. It can transport three-phase mixed materials such as steam, liquid, and solid. The viscosity of the medium that can be transported can reach up to 1000000CP and the slurry with a solid content of 55%. Compact structure, occupying less space compared to screw pumps.

Rotor type

Single blade rotor: suitable for conveying media containing large particles, with low crushing rate for large particles, but with high pulsation, low pressure, small volume, and rarely used.

Two blade rotor: suitable for conveying media containing small and medium-sized particles, with a relatively low crushing rate for small and medium-sized particles, slight pulsation, and a smaller volume than a three blade rotor.

Three blade rotor: a universal type of rotor with a larger volume than other types of rotors, and various performance indicators superior to single blade and two blade rotors, but it has a certain degree of crushing rate on granular materials during material transportation.

Four blade rotor: When the rotor blades exceed three blades, their volume decreases due to the increase of rotor blades. The more rotor blades there are, the less volume there is. Multi blade rotors have relatively improved stability when transporting materials, but they are prone to crushing granular materials during transportation.

Drive Type

Motor+Continuously Variable Transmission: High speed regulation accuracy, wide speed range (speed ratio can be changed freely between 1:1.4-1:7), continuous operation, smooth operation, stable performance, low noise, high torque, and infinitely adjustable flow rate. But its speed change needs to be manually adjusted, and the degree of automation is not high. The speed control must be carried out during operation, and the speed control handwheel should be turned when it cannot be stopped. It is not suitable for use in situations where overload or blockage may occur.

Motor+fixed ratio reducer: Strong load-bearing capacity, high efficiency, low vibration, low noise, low energy consumption, simple transmission mode, but due to its constant speed ratio, the flow rate cannot be adjusted.

Variable frequency motor+frequency converter: high torque, high speed regulation accuracy, smooth operation, stable performance, can be matched with automation systems to achieve automatic speed adjustment, ensuring arbitrary control of flow and compensating for the low degree of automation of continuously variable transmissions. The disadvantage is that the price of the frequency converter is relatively high.
