On October 17, Horse Tire announced that it had recalled 14,567 passenger car tires in the United States.

The models for these tires are the Cross Contact LX20 with the specification P275/55R20 111S and the production date is May 3-9, 2015.

It is reported that in the production process, the belt of these defective tires incorporates some impurities.

These potential impurities can cause a drop in rubber adhesion and damage the tread or belt.

It is understood that most of the tires recalled this time are equipped with universal pickup trucks and SUVs, and a small part is sold in the replacement market.

Horse brand tires have indicated that they have begun to contact users and dealers for free tire replacement.

Diaphragm Metering Pump

As the name suggests, diaphragm metering pump using a special design and processing of flexible diaphragm instead of the piston, under the action of the drive mechanism to achieve reciprocating motion, complete the suction - discharge process. Due to the segregation of the diaphragm, the isolation between the metering fluid and the driving lubrication mechanism is realized in the structure. High-tech structural design and the selection of new materials has greatly improved the service life of the diaphragm, coupled with excellent corrosion resistance of composite materials, diaphragm metering pumps become the main application of fluid measurement pump type.

In the diaphragm-type metering pump family members, the hydraulic diaphragm metering pump as a result of the use of hydraulic oil evenly drive the diaphragm, to overcome the mechanical direct drive mode under the pump diaphragm too concentrated shortcomings, to enhance the diaphragm life and working pressure ceiling. In order to overcome the single diaphragm metering pump may occur due to damage caused by the diaphragm damage, and some metering pumps equipped with a diaphragm breakage sensor to achieve the diaphragm when the automatic chain protection; with double diaphragm structure of the pump head to further improve its safety Sex, suitable for security protection is particularly sensitive to the application.

As a kind of diaphragm type metering pump, the electromagnetic driven metering pump generates the pulsating driving force with the electromagnet, which saves the motor and the speed change mechanism, makes the system compact and compact, it is an important branch of the small range low pressure metering pump.

Precision metering pump technology has been very mature, the fluid metering capacity of up to 0-100,000l / h, working pressure up to 4000bar, the scope of work covers all areas of industrial production requirements.
