Cartridges

Like filled Semkit systems, disposable plastic cartridges are available in 1, 2.5, 6, 8, 12, 20, 32 oz. and 1/10 gallon capacities. Available in low or high-density natural polyethylene, all sizes are fit with 1/4" NPT female thread dispensing orifice.

With plunger - CP and CWP cartridges are the standard Semco® cartridge with either a P-Plunger or WP (Wiper Plunger) inserted. This allows for filling from the dispensing end, reducing the potential for air entrapment and improving production rates.

Precision moulded plungers are available in three styles each with its own functional characteristics. All are designed to fit the cartridge contour, assuring complete dispensing and the elimination of waste. The WP or Wiper Plunger has the highest amount of interference. This provides the most complete wiping action on the cartridge inside diameter. The P-plunger has medium interference. It provides clean wiping action, inserts easily, and allows evacuation of entrapped air. 

The PRS or Pressure Relief Plunger has the least interference. It has been specifically designed to be easily inserted and reduce air entrapment during filling and dispensing. This dramatically reduces problems with dripping or stringing during dispensing.

Seals and Flange Caps are used to ensure retention of the plunger during shipping and storage. The Flange cap or F-cap is designed to fit over the large open end of the cartridge. There are three seal styles for the dispensing end. The TC-seal is a threaded part that matches perfectly with the dispensing orifice. The TS-seal contacts on three surfaces around and inside the dispensing end of the cartridge. The S-seal fits over the outside of the dispensing orifice only.

There are a number of different accessories and parts sold separately to fix general wear and tear and adapt dispensing systems to suit all applications.
