DULCOMETER® dialog
DACa Controller

The Hydro Hydraulic Diaphragm Metering Pumps are adjustable to a large range of most variable requirements thanks to its modular conception: single or double head version (optionally), 4 gear reductions, 2 liquid end sizes and 3 liquid end materials. Additionally, the Hydo offers internal pressure relief valve as well as multi-layer diaphragm with rupture detection for added safety.

 

Advantages

 

  • High process safety: multi-layer diaphragm with integrated diaphragm rupture detection as well as integrated hydraulics relief valve.
  • High process quality: metering reproducibility better than ±1 %
  • Further application area, flexibly adjustable to capacity requirement and medium to be dosed

 

Application Areas

 

  • Proportional metering of chemicals/additives in boiler-feed water treatment
  • Metering of reactants and catalysts in the chemical industry
  • Level-independent metering of adjuvants in the industrial production technology

 

Features

 

  • 2 sizes: Hydro/2 (capacity per liquid end 0.8 - 17.9 gph (3 - 68 L/h), 1450 - 362 psig (100 - 25 bar)) and Hydro/3 (capacity per metering head 2.6 - 449 gph (10 - 170 L/h), 1450 - 362 psig (100 -25 bar))
  • Available as single or double-head version
  • In double-head versions the liquid ends are operated in push-pull manner (boxer principle)
  • Each liquid end is equipped with a separate stroke length adjustment device so that each liquid end can be operated at an
    independent feed rate.
  • Standard operation: long range three-phase motor 230/400 V, 50/60 Hz, 0.37/0.75 kW, protection class IP 55
    (on demand ATEX-T3/T4), isolation class F
  • 4 gear reductions
  • Stroke length: 0.59" (15 mm), adjustable with 1% accuracy
  • Manual stroke length adjustment with optional actuator or speed controller
  • Stroke length adjustment manually (optionally with actuator or speed controller)
  • Gear housing: cast aluminum
  • Liquid end materials: PVDF, stainless steel, Hastelloy C
  • Multi-layer diaphragm with integrated diaphragm rupture signaling
  • Reproducibility of metering at defined conditions and correct installation better than ±1 % (stroke length area 20 - 100 %)
  • Preset pressure relief valve integrated in hydraulics
