Probes

Q: What probes exist and what are they used for?

Common variants include suction probes/dip tubes for material extraction from cups, cans or drums, circulation or return probes for circulating systems, as well as drum and container probes with venting. They ensure bubble-free delivery, short priming times, and a constant material flow to the gun or into the line.

Q: How do I select the right probe (length, Ø, connection & seals)?

Size according to medium/viscosity, delivery type (gravity, diaphragm/piston pump), container height, hose/thread connection and chemical resistance. Choose the length to match immersion depth, the outside diameter for the desired flow rate, and seals (e.g. FKM, EPDM, PTFE) according to solvent-based or waterborne materials.

Q: Which factors influence flow, priming behavior and service life?

Influences include probe length/Ø, surface roughness and material, seal geometry, connection thread, line routing (bends/heights), the medium’s viscosity/temperature, and whether a return/circulation is present. Check tightness, avoid air ingress, and replace wear parts (seals, check valves, strainers) on schedule.

Whether in industry, for car painting or in timber construction – beschicht. offers professional spray guns for every application.

Probes for Spray Guns & Material Supply | Suction Probes, Dip Tubes, Circulation/Return Probes | beschicht.®

Probes for Spray Guns & Material Supply

Discover suction probes & dip tubes for material extraction from cup, can or drum, circulation/return probes for circulating systems, as well as drum/container probes with venting. From length/Ø to connection thread/hose and seals through to materials – we match the probe to your medium, pump and process.

Use & benefits

Trouble-free material flow, short priming times and low-bubble delivery. Correctly sized probes stabilize flow, reduce air entrainment and impulse fluctuations, and ensure a reproducible application – in workshop and series production.

Technology & settings

Length & outside diameter: choose to match immersion depth and required flow rate. Connection (e.g. G 1/4, G 3/8, NPT, hose barb) to suit pump/line. Seals by medium: FKM/NBR for solvent-based media, EPDM for waterborne paints, PTFE for high resistance. Choose materials such as stainless steel, PTFE or HD-PE by chemical and abrasion resistance. Circulation/return reduces pulsation and keeps temperature/viscosity windows stable.

Accessories & integration

Container passthroughs, vents, check valves, strainer baskets, fittings/adapters, hose bundles, pressure gauges as well as cleaning & test media. We perform the compatibility check (connection, seal, medium) and integration in workshop and line.
