Ceramic Plunger

Our ceramic plungers are made of high quality imported raw materials, cold isostatic pressing forming way , and assembled with stainless steel metal parts after high temperature sintering. As one of the main components of the plunger pump, the cerami

Mgo Magnesia Zirconia Ceramic Plunger in Yellow Color An MgO (magnesia) zirconia ceramic plunger in a yellow color combines the excellent properties of magnesia and zirconia ceramics with a vibrant visual appeal. Magnesia ceramics provide high-temper

This ceramic piston with metal plunger made of zirconia ceramic + SST316L . It  is used on laboratory equipment is  at room temperature. The range inside could be 15-50 °C. The pressure at normal usage is atmospheric pressure + 2 / - 0.7 bar but could be +10 bar for short time in failure.

Waterjet intensifier ceramic plunger for water jet pump  with code 010253-1,  it is used on 60k ultra high pressure intensifier  waterject pump 50HP, 60HP,100HP, 40KPSI, 60KPSI  .   The max pressure it undertake can be 60 kpsi , voltage 220v/380v.

Because the industrial zirconia ceramic plunger has a series of advantages such as high temperature resistance, corrosion resistance, wear resistance and erosion resistance, it is widely used. What are the characteristics of the industrial zirconia  ceramic plunger?

The Alumina ceramic plunger is sliding  fit to the cylinder part ,  so the outside diameter tolerance is requested to be tight  to match with the cylinder .  The clearance between the piston and cylinder bore is 10 +6/-0 micrometer on the diameter .  The collar housing is made of 316 stainless steel material as it is more corrosion resistant and chemical resistant .  The plunger rod material is 99% alumina ceramic  which is wear resistant ,  high temperature resistance and can be used in harsh environment .

Characteristics of Battering Filling Ceramic Plunger  1. Using high purity and stable alumina , zirconia materials with resistance against acid and alkali corrosion .  2. Formed with cold isostatic pressing , sintered in hight temperature and precision machining , to ensure high density and zero porocity .  3. Assemble with the sleeve without leaking and locking .

This part as you can see on the picture , we have made a thread structure  on the Stainless Steel part ,  after we assembled with the zirconia cylinder in between , then we thread lock the two heads of the stainless steel part .  To make the connecting to be strong enough , we use some glue under the zirconia cylinder to make the connection more strong .

Zirconia Ceramic Piston Plunger  provide  precise sampling and reagent dispensing. With high aspirating and drainage accuracy, this series pump is a high performance, lost cost and maintenance free precision piston pump and its life time can be more than 5 million cycles without affecting the precision and accuracy. Piston pump has already been widely used in medical and laboratory analytical instruments.
