AODD PUMPS

Hygienic Series

Pharmaceutical industry, food and beverages, cosmetics

MAIN FEATURES

The DELLMECO “Hygienic Series” consists of air-driven diaphragm pumps specifically designed to meet the requirements of the food, beverage, pharmaceutical and cosmetic industries.

VIEW MANUALS

Quick to disassemble

  • The clamping system allows quick disassembly without the need for tools.

Smooth surface

  • The “sandwich” diaphragms have a completely smooth surface, which minimizes the risk of microbial growth. The diaphragms are available in food-safe materials - pure TFM (PTFE).

Superior finishing

  • Both the media side and the outer side are electropolished for a hygienic high-quality surface. Other special surface finishes are available upon request.

Eco air valve

  • The sealing system is completely lubrication-free, preventing contamination of both the pump and the environment.

Connectivity

  • As standard, the pump is supplied with connections according to DIN 11851. On request, the pump is also available with almost all common connection types within the hygienic sector, such as TriClamp, SMS, RJT, JIS or ANSI.

For CIP and SIP systems

  • Cleaning-In-Place (CIP) and Sterilization-In-Place (SIP) allow automatic cleaning and disinfection of the pump without extensive disassembly.

HOW TO INSTALL DELLMECO PUMPS?

Self-priming application

The suction height reaches up to 8 meters. This depends on the construction material used and the application parameters. All data are based on pumping water at 20 °C.

Underwater operation

Our pumps can operate fully submerged. However, the material used must be suitable for the surrounding liquid, and the outlet must be above the liquid level.

Positive suction pressure

Suitable for complete emptying of storage tanks, settling tanks or similar containers. The optimum inlet pressure is between 0.2 and 0.3 bar.

RECOMMENDED INSTALLATION GUIDELINES

To reduce stresses on piping and pump connections, we recommend using flexible couplings on both the suction and discharge lines and the air connection. For optimum performance, DELLMECO recommends installing a pulsation damper on the discharge side of the pump.

Without pulsation dampeners

With pulsation dampeners

  • Connect a flow-through valve and a drain valve to the fluid outlet of the pump.
  • Connect a maintenance valve to the fluid supply (suction side) of the pump.
  • Connect a hose to the valve on the suction side and the valve on the discharge side of the pump.
  • Connect a hose from the suction side and the discharge side of the pump to the respective tanks or reservoirs.

TECHNICAL DATA

DIMENSIONS OF HYGIENIC PUMPS

CAPACITY OF HYGIENIC PUMPS

The viscosity of the medium affects the pumping capacity.
The capacities listed in the pump characteristics are based on water (1 cPs).
When pumping media with higher viscosity, the volume must be reduced accordingly.

HOW TO CHOOSE THE RIGHT PUMP SIZE

1. Enter the desired flow rate and pressure required.
(example: 50 l/min and 4 bar)
2. Read the estimated energy consumption in volume and pressure.
(example: 0.40 Nm³/min at 6 bar)
