ARO supplier in Romania
For ARO we quote EXP and PRO series diaphragm pumps, EVO 200 and EVO 300 electric pumps, diaphragm kits and ARO-Flo FRL units; we need the complete code from the pump and the liquid handled.
Who is ARO and what does it make?
ARO makes pumps and equipment for fluid transfer: air-operated double diaphragm pumps, EVO electric diaphragm pumps, piston pumps, drum pumps, centrifugal and gear pumps, condensate pumps, plus filter-regulator-lubricator (FRL) units, lubrication equipment, valves and pneumatic cylinders. Diaphragm pumps transfer low- and medium-viscosity liquids in chemicals, energy, pharmaceuticals, mining and general manufacturing, including in ATEX zones. For a quotation, send us the complete code from the pump (for example PD05P-…), the liquid, the flow rate and the available air pressure.
Air-operated double diaphragm pumps work without stalling and without the air motor freezing. The EXP series, from 1/4 to 3 inch, has a patented air motor and broad chemical compatibility, and can take control through a solenoid valve, flow monitoring and leak detection; it reaches about 1079 l/min at 3 inch. The PRO series, from 1 to 3 inch, is for general industrial use and for machine builders, with flows of up to 897 l/min, while the stainless steel sanitary pumps, from 1/2 to 3 inch, are for the food and pharmaceutical industries. The EXP code begins with PD (standard version) or PE (version with electronic interface), followed by the connection size: 01 for 1/4 inch, 03 for 3/8, 05 for 1/2, 07 for 3/4, 10 for 1, 15 for 1 1/2, 20 for 2 and 30 for 3 inch.
EVO electric pumps need no compressed air: EVO 200, 1 inch, with two diaphragms, for transfer, batching and dosing, and EVO 300, 1 and 2 inch, with three diaphragms, for continuous 24/7 processes, with a frequency inverter, secondary containment housing and leak detection. Piston pumps, hydraulic or pneumatic, transfer and extrude viscous fluids, and lubrication pumps mount on containers from buckets to drums, for oils and greases. ARO-Flo FRL units and pneumatic cylinders – composite, round repairable or non-repairable and square interchangeable NFPA – complete the range.

Why ARO?
- Diaphragm pumps without stalling and without air motor freezing — continuous operation in transfer
- EXP series with solenoid valve, flow monitoring and leak detection — the pump integrates into automation
- EVO 300 with three diaphragms and frequency inverter — for continuous processes without compressed air
- EXP code indicating the version and connection — the replacement is identified straight from the nameplate
- Pumps, FRL, lubrication and pneumatic cylinders from the same brand — a single parts list for the fluid installation

How do we supply ARO in Romania?
We can quote ARO air-operated and electric diaphragm pumps, piston pumps, repair kits (diaphragms, balls, seats), ARO-Flo FRL units and pneumatic cylinders. For identification we need the complete code from the pump nameplate, which contains the size, the materials and the diaphragms; for a new application, the liquid and its viscosity, the flow rate, the pumping head, the air pressure and the zone classification. We bring the pumps in to order, by import or through EU channels, usually in 1–4 weeks; kits take 24–72 h when the item is available locally or at the supplier. The exact lead time is confirmed in the quotation.
The materials of a repair kit are determined from the complete pump code, because diaphragms, balls and seats differ from one design to another.
Frequently asked questions about ARO
What does ARO make?
ARO makes air-operated double diaphragm pumps (EXP, PRO, sanitary), EVO electric diaphragm pumps, piston pumps, drum pumps, centrifugal, gear and condensate pumps, lubrication equipment, ARO-Flo FRL units, valves and pneumatic cylinders.
How do I choose between an air-operated pump and an EVO electric one?
The air-operated pump suits flexible transfer, hazardous zones and variable production. EVO 200 is for batching and dosing where there is no compressed air, and EVO 300, with three diaphragms and a frequency inverter, for continuous 24/7 processes.
How long do we wait for an ARO diaphragm kit or pump?
Yes. Repair kits and common pumps take 24–72 h when the item is available locally or at the supplier; the other ARO pumps we bring in to order, usually in 1–4 weeks. For special designs or configured EVO pumps, depending on the brand and the specifications, the lead time may be longer.
How do I find the right diaphragm kit for my ARO pump?
The complete code on the nameplate indicates the size, the body material, and the materials of the seats, balls and diaphragms. Send it to us or a clear photo of the nameplate, and we will identify the kit; from the code we confirm the compatibility of the materials with the liquid pumped.
What should I send for an ARO diaphragm pump quotation?
The liquid and its concentration, the viscosity, the temperature, the flow rate wanted, the discharge head, the available air pressure, the connection size, any presence of solid particles and the classification of the installation zone. With this data we choose the EXP or PRO series, and the right size and materials.
How do I request a ARO quotation?
Send the ARO code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
