Hydraulic seals, also called hydraulic cylinder seals or shaft seals, are parts used to keep fluids from escaping from cylinders, at the same time preventing contaminants from entering into cylinders.

 

They are critical parts in many types of machinery since they help create a method for fluid power to be converted into linear motion. These seals need to be designed and produced to withstand high pressure, or even high temperature in many of industries, in this case, the function of Hydraulic seals is not only preventing leakage of fluid from the Cylinder, it is also challenging for seals.

 

There’re combinations of seals, including hydraulic rod seals, hydraulic piston seals, wear rings or guide rings, scrapers or wipers. The functions of each are different.

 

The jst-seals rod seals prevent leakage of fluid from within the cylinder to the outside; Hydraulic Piston seals prevent fluid from flowing across the cylinder head; Wear rings guide the piston and piston rod within the hydraulic cylinder; Wipers scrape dirt or chips from the piston rods preventing contamination.

 

JST supply various types of hydraulic seals, and we’re able to do the tests related to temperature, pressure, tensile strength, reciprocating, etc. You’re welcome to reach our sales for price lists.

 

BONVE INLINE HIGH SHEAR EMULSIFYING AND HOMOGENIZING MIXER is a high-efficiency mixer integrating mixing, dispersing, crushing, dissolving, refining, depolymerizing, homogenizing and emulsifying.

Both colloid mill and homogenizer mixing pump can shear, emulsify, disperse, and mix materials, but in fact, colloid mill and homogenizer mixing pump are two kinds of equipment based on the principle, structure, and application.

Colloid mill is a kind of grinding equipment, suitable for materials with higher viscosity and larger particles. The working principle of the colloid mill is that the motor drives the rotor and the stator to rotate at a relatively high speed. When the processed material passes through the gap between the stator and the rotor, it is subjected to strong shearing force, frictional force, high-frequency oscillation and other physical effects. The material is effectively emulsified, dispersed and crushed to achieve the effect of fine crushing of the material.

Emulsification pump is a kind of emulsification equipment, which is suitable for materials with small particles. The working principle of the emulsification pump is that the material undergoes a series of processes such as strong shearing, impact and turbulence between the homogenizer rotor and the stator that rotate at a high speed, so that the material can withstand hundreds of thousands per minute in the narrow gap between the stator and the rotor. Times of hydraulic shear. The combined effects of centrifugal extrusion, impact and tearing can instantly evenly disperse and emulsify. After high-frequency cyclic reciprocation, high-quality products with no bubbles, fineness and stability are obtained.

From the above point of view, the difference between the two in terms of the refinement effect, the mixed homogeneous emulsification pump is better than the colloid mill. Generally, in many occasions, the colloid mill is used in the front of the emulsification pump or in the high In the case of viscosity, colloid mills are often used for refinement when there are many solid substances. Therefore, when choosing colloid mill and emulsification equipment, you still have to refer to your own production materials.

Bonve homogenizer mixing pump’s working chamber is composed of a total if 12 layers of three-stage rotor and stator. Proceed products are dispersed, refined and emulsified by the rotor and stator in stages. The pump is an high efficiency ultra-fine homogeneous pump with mixing, dispersion, breaking, dissolution, refinery, homogenization, emulsifying and transporting. The sealing of Bonve homogenizer mixing pump can be either double face or single face according to the properties of the processed materials. It also can have heating insulation or cooling device if required by the users.

Bonve homogenizer mixing pump is suitable for large and medium batch continuous online production or cyclic processing production process.

Gear pump is a positive displacement pump, which has a pair of meshing gears. One driving gear is driven to rotate by the motor, and the other driven gear is meshed with the driving gear to rotate. When the two gears are gradually separated, a partial vacuum will be formed. The liquid is inhaled through the suction pipe under the action of atmospheric pressure, and the inhaled liquid is squeezed and pushed out by the gear along the inner wall of the pump, which features small handling and high lift.

Gear pumps use conveying media as the lubricating medium in rotation, and are generally used in oily media, otherwise they will cause great wear and reduce the service life to a large extent.

Rotary lobe pump consists of two lobe rotors, which rotate synchronously driven by a pair of synchronous gears in the gearbox. The rotors are driven by the main shaft and sub-shaft to rotate in a synchronous reverse direction, which changes the pump capacity, builds up high vacuum and discharge pressure, thus an efficient pumping is formed. Gap is kept between the rotors and between the pump casing. There are basically no vulnerable parts during operation, and it is easy cleaning and maintenance. It is the first choice for customers in liquid transportation at present.

Rotary lobe pump is used to transport the medium according to the volume change between the rotor and the pump casing, and can transport the medium with viscosity below 100000 CP. Applicable in food, daily chemical industry, fine chemical industry, papermaking, medicine and pharmacy, environmental protection, petroleum and other fields.

Below table shows the main difference between gear pump and rotary lobe pump:

Details	Rotary Lobe Pump	Rotor Gear Pump
Application	High viscosity, high density, high solid products	General for oil products
Structure	Gap is kept between the rotors and between the pump casing, no friction, long life, no damage, no physical and chemical reaction to the pumped products.	Gears mesh together, hard contact, wear. Flow efficiency decreases after wearing, short service life.
	Simple structure, low failure rate, easy to maintain.	The front end has a shaft sleeve, which is easy to wear. The pump needs to be disassembled for replacement, and the maintenance is complicated.
Spare Parts for Maintenance	Mechanical seal and O-ring	Mechanical seal and O-ring
	/	Shaft sleeve
