Single and Two Speed Hydraulic Hand Pumps Features


Single Speed Hydraulic Pump

                        A single-speed hydraulic hand pump is a simple and comparatively low-cost option and as you pump the lever, the hydraulic oil is drawn from the pump’s tank towards your hydraulic tool which may be a hydraulic cylinder, puller, or a press. When using a single-speed hydraulic pump with a big tool such as a cylinder, the plunger will develop by the same amount with each stroke of the pump’s handle. The reason for this is that the amount of oil banished per full stroke is always the same. For many applications, this is precisely what is required. But for projects where a big cylinder or other tool needs to extend large distances, this can be very much time-consuming and tedious and this is when a two-speed pump can save a day.

Two Speed Hydraulic Hand Pumps

                              A two-speed hydraulic hand pump switches from an early low-pressure, high oil movement stage to a low-displacement and high-pressure stage. When used with a hydraulic cylinder, this means the better oil flow in the first stage moves the cylinder needle a longer distance with each stroke. When it reaches the switch pressure, the two-speed pump changes from low to high-pressure pistons characteristically when the cylinder reaches the load and starts working harder. A two-speed hydraulic hand pump can be more beneficial than a single-speed one for applications such as weight testing, hydraulic press, and long-stroke cylinder. However, they are not suitable for jobs needful high pressure all the way.

Single-Speed and 2-Speed Hand Pump Comparison

                                A single-speed hydraulic pump delivers low flow with high pressure which is usually fine for lesser stroke hydraulic cylinders, flange spreaders, and pullers. A two-speed hydraulic hand pump makes high flow at lower working weights and can also provide lower flow when it reaches the advanced working pressures. This is particularly useful when the cylinder plunger or any other hydraulic tool has far to travel earlier than the real work begins. Associated with a single-speed pump, some two-speed types can decrease the number of handle strokes by as much as 78 percent. Both types of pumps are obtainable with different oil capacities, and in outlines to suit tools requiring both single and double-acting hydraulic flow.

How Do a Two Speed Hydraulic Hand Pumps Work?

                              A two-speed pump is a hydraulic pump that usually contains a safety relief regulator and has an internal setting for a pressure switch. Characteristically, it creates more flow at lower working pressures and lowers flow at advanced working pressures. This allows for the finest efficiency across increasing pressures in hydraulic cylinders or some other hydraulic applications. When it starts in a manual hydraulic tool, the two-speed pump is typically favoured as it allows for a lower handle effort at advanced pressures, here is how it works:

Functions of a Two Speed Hydraulic Hand Pumps

                            The two-speed pump’s relief valve is usual to a pressure which is typically referred to as a substitution pressure. When the pressure upsurges in the cylinder or hydraulic system and reaches the exchange pressure, the two-speed pump switches from low to the high-pressure piston. A two-speed pump will change from low to high-pressure pistons when the cylinder hits the exchange pressure which is 200 PSI for example as the pressure is increasing. This exchange will occur automatically internally. In RIVERLAKE HYDRAULIC manually operated hand pumps come in aluminium or in steel. The HP227 and HP232 two-speed pumps are some of the most common, manual hydraulic pumps, and their operation can be learned easily.

Advantages of a Two Speed Hydraulic Hand Pumps

                                 While a two-speed pump is typically a higher cost than a single-speed pump, a two-speed pump bids many advantages. For instance, it is easier to operate physically at higher pressures, with fewer requests on the operator. The RIVERLAKE HYDRAULIC manually operated two-speed pumps come in a variety of models and most models features two-way valves, but four-way valves are also available. With their relaxed operation and lightweight design, these pumps are a great choice for all. The result which everyone chooses is the pumps that are easy to operate, easy to repair, and service which helps in saving time and money for our customers. The life expectancy of RIVERLAKE HYDRAULIC products leads the market and our pumps provide power that lasts for generations. Hydraulic hand pumps are very lightweight, and portable, and they do not require an external power source. These pumps are cost-effective, very easy to use, and ideal for workshop or field use applications.

Types of hydraulic pumps

Air hydraulic pump

                               A cost-effective option for quicker and more efficient operations. No manual effort is essential by the operator. Portable and perfect for workshop use, only standard air-line supply is obligatory. Field use is possible if access to a compressor is available.

Electrical hydraulic pump

                             The finest option where large capacities of oil are required: e.g., multiple cylinder operations. With the addition of diverse valve types, these pumps can effortlessly operate multiple tools. The electric pumps are appropriate for stationary installations.

Petrol hydraulic pumps

                          An excellent alternative where field operations are obligatory: e.g., construction sites and shipyards.
