Desoldering pump CJ-101

Overview

The CJ-101 Desoldering Pump (Solder Sucker) is an indispensable workbench tool engineered for fast, clean, and effortless removal of molten solder from circuit boards, through-hole components, and solder joints. Featuring a powerful internal spring-loaded piston mechanism and a heat-resistant PTFE Teflon nozzle, this manual vacuum pump creates instant, high-velocity suction at the press of a release button. Whether you are salvaging rare microcontrollers, correcting a bridged PCB pin, or desoldering multi-pin switches, the CJ-101 clears solder holes completely in a single stroke without lifting delicate copper traces.

Key Features

• High-Power Spring Suction: Heavy-gauge compression spring delivers instantaneous negative pressure, pulling molten solder deep into the internal chamber.
• Heat-Resistant Teflon Tip: Resilient PTFE nozzle withstands direct contact with 300°C–400°C soldering iron tips without melting or deforming.
• Ergonomic One-Handed Operation: Thumb-activated release trigger and textured cylindrical grip allow seamless one-handed cocking and firing while holding your soldering iron.
• Easy Disassembly & Cleaning: Simple twist-lock body unscrews in seconds, allowing you to empty collected solder waste and lubricate the piston seal.
• Double-Seal Air Tightness: Precision internal rubber plunger maintains tight vacuum seals over thousands of repetitive compressions.
• Anti-Static & Safe: Protects sensitive semiconductor gates and IC pins against electrostatic buildup during component rework.

MOKWN Recommendation

Don't ruin a good PCB trying to flick away molten solder with wires or toothpicks! The CJ-101 solder sucker is one of the cheapest yet most essential tools you can own at your electronics station in Egypt. Pro-Tip from MOKWN: When desoldering stubborn factory lead-free joints, add a tiny bit of fresh leaded solder to the joint first. This lowers the melting point and allows the CJ-101 to vacuum the hole 100% clean in one quick snap. Order your CJ-101 today from MOKWN with rapid delivery to your door!
