Code System

Viscosity and Pump Capacity
The capacity specified in the pump performance charts generally refers to water (1 mPa•s). The value must be reduced correspondingly when pumping media with higher viscosity. The design capacity can be read off directly from the graph and the corresponding pump size selected.
The example shown here is based on a required capacity of 10 m3/h with a product viscosity of 6000 mPa•s. The dash-dotted line intersects the design capacity scale at 17 m3/h.
When handling viscous media, the highly increased necessary suction capacity has to be taken into consideration also. A sufficient size of cross-sections in the suction piping helps to avoid gasing as well as capillary effects. For media with high viscosity a mild positive suction pressure is to recommended.

Performance Range
The data refer to water (20 °C), under using of different variations (e. g. ball valve model, damper preparation etc.), a compressor Atlas Copco VSG30 and calibrated measuring equipment. The specified performance data are warranted by ALMATEC in accordance with DIN EN ISO 9906.







- Compatible liquids include sludges, acids, alkalis, solvents, slurries, emulsions, mixtures of liquids and solids, resins, powders, aqueous solutions.
- These liquids may be of high or low viscosity, abrasive, thixotropic, hazardous, toxic, non- lubricating, hot, cold, coagulating, shear sensitive, pasty, solids containing, corrosive.
- The fields of application include chemical industry, pharmaceuticals, cosmetics, ceramics, surface treatment, emergency services, power plants, refineries, mechanical engineering, textile industry, water processing, waste disposal, paper industry, electronics, solar industry.
Options
Meeting Special Application Requirements
A variety of quality optional equipment completes the Almatec® pump program, and allows a precise set up for your specific application.
Barrier Chamber System (Code BS)
The Almatec barrier chamber system meets high-safety requirements. The individual diaphragm is replaced by two diaphragms arranged in tandem with a barrier chamber of conductive PE between them and filled with non-conductive liquid. A change in conductivity of the barrier liquid is detected by sensors and signaled to a controller, which triggers an alarm or disconnects the pump.

Stroke Counting (Code C)
Almatec air-operated diaphragm pumps can be used continuously (24-hour operation) or intermittently for hours, for minutes or for an exact defined number of strokes. To accurately count the strokes, a sensor can be installed in the pump’s center housing (also available as pneumatic version)
Diaphragm Monitoring (Code D)
A capacitive sensor installed in the pump muffler detects all liquids and in case of a diaphragm rupture it outputs a corresponding signal to a controller which then triggers an alarm or disconnects the pump via a connected solenoid valve.

Flange Connection (Code F)
According to recognized industry safety standards, all E-Series pump sizes from E 15 to E 50 can be equipped with thread bushings and flange O-rings for flange connections DIN or ANSI / PN 10. For the AH Series pumps, the flange connection DIN or ANSI / PN 16 is standard.

Draining System (Code R)
E-Series pump sizes E 15 to E 50 are available with a special Almatec draining system consisting of a bypass system in the side housings that can be activated easily either via hand-operated valves or pneumatically. In this way, the pump and piping can be drained without having to be dismounted. The amount of cleaning agent and solvent required when changing products is considerably reduced, and this greatly reduces environmental pollution. For metal CHEMICOR pumps, another constructive solution is available. Ball lifters – which are turnable by hand – are fitted to the four ball valves. By turning the handles, the ball valves are lifted out of their seats.
