Who is Wilden and what does it make?

Wilden is the American manufacturer that invented the air-operated diaphragm pump (AODD) in 1955. The main range, the Pro-Flo series, covers clamped models (P.025 to P8) and bolted-flange models (P100 to P1500 in plastic, P220-P830 in metal), for transferring liquids without a dynamic seal, directly from vessels, tanks or process lines. For Romania, Wilden means access to a pumping technology without bearings or rotary seals — useful where maintenance must be simple and quick.

What sets the Pro-Flo SHIFT series, the advanced version of the range, apart is its own air distribution system. Alongside the standard series, Wilden also offers specialised pumps — Saniflo for the food and pharmaceutical industry, FDA, high-pressure or mining variants — plus FDA and 3-A certifications for hygienic applications and CSA/UL for special areas.

Wilden makes sense where the liquid contains solid particles, is abrasive or requires self-priming without an additional centrifugal pump — transfer of paints, adhesives, slurries or viscous food products, in installations where stoppage for maintenance must be minimised.

What do we supply from the Wilden range?

Product	Description
Pro-Flo Clamped Metal/Plastic (P1-P8)	The base family of the Wilden range, with connections from 13 mm (1/2") to 51 mm (2"), available in both metal and plastic, with a clamped design for quick disassembly without special tools during service interventions. Recommended as a starting point for most industrial transfer applications where a very high flow range is not needed.
Pro-Flo Bolted Plastic (P100-P1500)	Bolted-flange variant of the plastic range, from 13 mm (P100) to 76 mm/3" (P1500), for installations where sealing with a bolted flange is preferred over the clamped system. It covers a wider size range than the clamped series, useful at higher flow rates or in larger-diameter piping.
Pro-Flo Bolted Metal (P220/P420/P820)	Bolted metal variant, in steps of 25 mm (P220/P230), 38 mm (P420/P430) and 51 mm (P820/P830), for environments where the mechanical strength of the metal housing matters more than the low weight of plastic. A typical choice for fixed industrial installations with high line pressure.
Turbo-Flo (Specialty Series, e.g. T4)	Pump from the Specialty series for utility applications, with a 38 mm (1-1/2") connection on the T4 model in clamped metal version. It is part of the range of pumps dedicated to specific niches (utility, sanitary, high pressure, mining) that complement the standard Pro-Flo series.

How do we supply Wilden in Romania?

We supply Wilden pumps from the Pro-Flo series and specialised ranges (Saniflo, high-pressure) through supply channels in the EU and the USA, to order. For this brand we work from the manufacturer's technical documentation and confirm each configuration (material, connection size, diaphragm type) through our supply channels before quoting. To order, typically 1–4 weeks from order confirmation (Wilden). For an accurate quotation we need: the liquid pumped, the connection size desired, the contact material required and whether the application calls for FDA certification or another sanitary standard. The Saniflo and high-pressure variants are supplied to order; none is kept on our shelves.

We check the availability of diaphragms and service kits for each material variant through our supply channels.

Frequently asked questions about Wilden

What product range does Wilden have?

Wilden makes air-operated diaphragm pumps (AODD), without a dynamic seal, in the base Pro-Flo series, the advanced Pro-Flo SHIFT version and specialised ranges for the food and pharmaceutical industry or high-pressure applications.

What is the difference between Pro-Flo and Pro-Flo SHIFT at Wilden?

Pro-Flo SHIFT is the advanced version of the range, with its own air distribution system.

How do I choose the right size of Wilden pump?

The size is chosen according to the flow rate needed and the diameter of the connection in the installation: the Pro-Flo series covers from 6 mm (P.025) to 76 mm (P1500), and the choice of material (metal or plastic) depends on the chemical compatibility of the liquid.

Do you supply Wilden pumps in Romania and how quickly?

Yes, we bring Wilden pumps in to order through supply channels in the EU and the USA; the lead time is typically 1–4 weeks, depending on the configuration confirmed through our supply channels.
