Motor Power: 0.18 or 0.25 kW
Frequency: 60 to 120 strokes/min at 50Hz, 72 to 144 strokes/min at 60Hz
Pump Head Materials: PP, PVC, SS316, or PVDF
Valves: Single ball with ceramic or SS316L balls
Ball Seats: FPM, EPDM, or NBR
Valve Seats: PVC or PVDF
Diaphragm Material: PTFE
Housing: Die-cast aluminum with epoxy/anti-acid paint
Protection Degree: IP55
Insulation Class: F

Optional Features:

Motorizations: Options include UL/CSA motor certification, single-phase motor, self-ventilated motor, ATEX motor, and tropicalized motor.
Hydraulic Options: NPT hydraulic connections and larger dimension valves.
Regulation and Control: Electric actuator and inverter for automatic adjustment via a 4-20mA signal.

Technical Features:
The document provides detailed technical specifications for various models, including flow rate, pressure, strokes per minute, membrane size, power, and valve types. For example, model AD0016 has a flow rate of 16 l/h at 50Hz and 19 l/h at 60Hz, with a maximum pressure of 14 bar.

Pump Head Configurations:

Standard and on-request configurations are available with different materials for head, connections, diaphragm, valve seats, balls, and ball seats.
Standard configurations include materials like SS316L, PP, PVC, and PVDF.
On-request configurations offer additional material options for specific components.

Model Codes:
The document lists model codes with descriptions, indicating flow rate, pressure, and head material, such as AD0016CA00100 for a 16 l/h, 14 bar pump with a PP head.
