Almatec Eseries Diaphragm Pumps

The Almatec E-Series represents the latest generation of plastic air-operated double diaphragm pumps made in solid design. Compared to the predecessor A-Series the following advantages are applicable:

  • further increased pump safety due to innovative ring-tightening structure
  • increased capacity
  • decreased air consumption
  • reduced noise level
  • optimized flow pattern
  • pulsation damper suitable for flange connection

The housing parts are tightened to each other via housing bolts. However, instead of single bolts pressing at single points against the housing, all housing bolts are now tightened against a diaphragm-sized ring on each side. This structure results in a more even distribution of the housing bolt force and in an increased permissible bolt torque - in the end an increased pump safety which is assisted by further improvements of construction details.

The flow resistance is reduced via an optimised flow pattern to increase the efficiency factor of the pump. Compared to the A-Series, the same air flow achieves a higher fluid flow; respectively less air flow is required from the same fluid flow.

The pulsation damper can still be used an integrated model on top of the pump. However, an additional version with flange connection is available.

For the E-Series pumps the following materials are available:

  • Housing: PE, PE conductive, PTFE, PTFE conductive
  • Diaphragms: EPDM, PTFE/EPDM, NBR
  • Ball valves: EPDM, PTFE, NBR, stainless steel
  • Cylinder valves: PTFE

E-Series pumps made of PE conductive and PTFE conductive meet the ATEX requirements of the directive 94/9/EG.

The seven pump sizes achieve the following max capacities:

  • 0,9 m³/h, 15 l/min, 4 gpm (E08)
  • 1,4 m³/h, 23 l/min, 6 gpm (E10)
  • 3,4 m³/h, 55 l/min, 15 gpm (E15)
  • 8 m³/h, 130 l/min, 35 gpm (E25)
  • 20 m³/h, 330 l/min, 88 gpm (E40)
  • 36 m³/h, 600 l/min, 160 gpm (E50)
  • 48 m³/h, 800 l/min, 210 gpm (E80)

The features of the E-Series at a glance:

  • air-operated diaphragm pumps in solid design
  • housing made of PE or PTFE, both also available in a conductive version
  • interchangeability to the A-Series
  • seven sizes from DN 8 to DN 80
  • max. capacities of 0.9 to 48 m³/h
  • increased pump security due to innovative ring-tightening structure
  • compared to the A-Series, increased capacity and decreased air consumption thanks to the optimized flow pattern, decreased noise level
  • ATEX conformity
  • exterior free of metal
  • optimized diaphragm fixing
  • different possible port configurations
  • ball or cylinder check valves with identical interior design
  • maintenance and lubrication-free air control system PERSWING P® without dead center
  • composite diaphragms with integrated metal core, no diaphragm discs
  • proof against dry running and overloading, self-priming, insensitive to solids
  • gentle displacement
  • can be infinitely controlled via the air volume
  • no drives, no rotating parts, no shaft seals
  • unattended operation with long service life
  • easy to start up
  • integrated muffler
  • recessed tie rods
  • vibration dampers with female thread on the underside for simple direct installation
  • low noise levels
  • optional features meeting requirements
  • screw-on or flanged pulsation damper
  • back flushing system
  • barrier chamber system
  • diaphragm monitor
  • stroke counter
  • flange connection
  • transport cart
