Manual hydraulic pumps are a good choice when portability and cost are important considerations. With the help of our simple, single-stage, compact hand pumps which come in a variety of sizes, it is possible to pump large cylinders efficiently without the need for an external power source. There are several models of plastic pumps on the market today, but there are also some models available in aluminum, so you can benefit from the weight saving of a plastic pump without sacrificing the durability of an aluminum pump.
