Product Name : Stainless Steel Sanitary Hygienic Two Stages Single Screw Pump with Fix Speed Motor
Sanitary screw pump is a single-screw transport pump. Its main working parts are the screw of the eccentric screw (called the rotor) and the screw bushing (called the stator) with the inner surface of the double helical surface. Its working principle is that when the motor drives the pump shaft to rotate, the screw rotates around its own axis on the one hand, and on the other hand it rolls along the inner surface of the bushing, thus forming the sealed chamber of the pump. Each time the screw rotates once, the liquid in the sealing cavity advances by a pitch, and with the continuous rotation of the screw, the liquid is pressed from one sealing cavity to the other sealing cavity in a spiral manner, and finally squeezes out of the pump body. Sanitary Single Screw Pump is used for in all fields widely to feed kinds of medium, running at a constant pressure continuously, without pulse and damage when feeding medium , and change the gauging aim through adjusting rotation speed.
Feeding Medium
This products is applicable for feeding medium which has the following properties
High solid content (diameter of the biggest particle is 50mm) or no soild content
Medium with all viscosities (1mPas ~ 300000mPas)
Medium that is easy to be generated and swelled
Shearing sensitive medium
Medium with erosion
Medium with/without self lubrication
Erosive medium (PH=1~14)
Adhesive medium
Toxicity hazard medium

Application
Food industry: ketchup, mashed potatoes, peanut butter, yogurt, fresh cream, ice cream, cheese cubes, whey, beer, wort, yeast, fruit juice drinks, vegetable paste, jam, jelly, etc.
Petroleum industry: conveying crude oil, mixture of crude oil and water, mixture of coal field gas and water, etc.
Advantages
| 1 | Wide range of pressure and flow. The pressure is about 3.4-340 kgf/cm2, and the flow rate can reach 18600cm3/min |
| 2 | The type and viscosity range of the conveyed liquid are wide |
| 3 | Because the inertial force of the rotating parts in the pump is low, it can use a high speed |
| 4 | Good suction performance and self-priming ability |
| 5 | Uniform and continuous flow, low vibration and low noise |
| 6 | Compared with other rotary pumps, it is less sensitive to incoming gas and dirt |
| 7 | Solid structure and installation Maintenance is easy |
