Desoldering Pump

The DP-366P is a powerful manual desoldering pump with a rear-pull spring mechanism. Pressing the release button produces instantaneous suction for circuit-board desoldering and removal of residual solder from larger joints. The nozzle is replaceable and the unit can be disassembled for cleaning.

It is suitable for electronic repair, training, and DIY desoldering, particularly on multilayer PCBs or joints with larger amounts of solder. Performance still depends on fully melting the solder and achieving a good nozzle seal.

Official information lists the DP-366P/DP-366A as high-suction desoldering pumps with suction greater than 38 cm-Hg, suitable for multilayer boards or larger joints. Position the nozzle close to fully molten solder during operation.

The rear plunger compresses the spring and the button releases it instantly, while the non-slip grip supports one-handed control. Keep fingers away from the nozzle and release mechanism while cocking the pump.

Cock the pump, melt the joint completely with a soldering iron, place the nozzle close to the molten solder, and trigger it immediately. If solder remains, add flux and repeat without heating the pad for an extended period.

Yes. The nozzle is a replaceable and cleanable component. Confirm that replacement dimensions and heat resistance are compatible. A cracked, deformed, or poorly sealing nozzle reduces suction.

Wear safety glasses, point the nozzle toward the joint and away from the face, and do not touch the nozzle or solder immediately after heating. Keep the work area ventilated and ensure that the circuit board is de-energized.

Open the solder-collection chamber, remove solder debris, and inspect the nozzle, piston, and seals. Apply a small amount of lubricant to sealing parts according to the instructions. After reassembly, perform a dry suction test to confirm normal plunger and button operation.

The DP-366P emphasizes stronger suction and larger solder joints. A small pump is more portable and suitable for occasional fine joints. For continuous high-volume desoldering, an electric desoldering station is generally more efficient.

Confirm availability of replacement nozzles and seals and the required cleaning method, and check the actual set contents. Packaging may vary by batch or market, so refer to the product page and physical package.
