Hydro Hydraulic Diaphragm Metering Pump

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. And additionally, safety as a standard: bypass valve as well as multi-layer diaphragm with diaphragm rupture signaling.

Advantages

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

Application areas

• Quantity-proportional dosing of chemicals/additives in boiler-feed water treatment
• Dosing of reactants and catalysts in the chemical industry
• Level-independent dosing of adjuvants in the industrial production technology e.g. dosing of hot cera in the production of adhesive tapes

Features

• 2 sizes: Hydro/2 /capacity per liquid end 3 - 68 l/h, 100 - 25 bar) and Hydro/3 (capacity per dosing head 10 - 170 l/h, 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: 15 mm, adjustable with 1% exactitude
• Stroke length adjustment manually (optionally with actuator or speed controller)
• Gear housing: aluminium cast
• Liquid end materials: PVDF, stainless steel 1.4571, Hastelloy C
• Multi-layer diaphragm with integrated diaphragm rupture signaling
• Reproducibility of dosing at defined conditions and correct installation better than ±1 %
  (stroke length area 20-100%)
• Preset bypass valve integrated in hydraulics
