This third function kit allows you to add an additional hydraulic function to your tractor or skid loader without the need for expensive factory add-ons.

The valve can be installed on any equipment that has a power beyond port on it pending the flow is less than 15 GPM. If no power beyond port is available or can’t be identified, this valve can be connected directly to the hydraulic pump with the loader valve connected downstream.

This kit has variations that can be selected using the drop-down menu’s above. The variations are whether you’d like hydraulic fittings (used to connect hydraulic hoses) included in the kit or not, and what type of quick connect couplers you’d like included with this kit.

To connect this third function kit four hydraulic hoses are needed. Pressure Line (Inlet), Tank Line (Outline), (2) work-lines (lines to cylinder). The chart below shows the hoses needed for each kit we sell. The type of hoses are shown below, however you’ll need to measure your machine for the correct lengths. The (2) work-line hoses will be the same length and go to the front of your machine, The pressure and tank lines will need to connect to your power beyond (pressure) and go back to the hydraulic tank (return). See the diagrams below for more information on connecting this valve. Note:Hose lengths will be dependent on where the valve body is mounted.

In waterworks and wastewater systems, pumps are commonly installed at the source to raise the water level and at intermediate points to boost the water pressure. The components and design of a pumping station are vital to its effectiveness. Centrifugal pumps are most often used in water and wastewater systems, making it important to learn how they work and how to design them. Centrifugal pumps have several advantages over other types of pumps, including:

A centrifugal pump consists of a rotating shaft that is connected to an impeller, which is usually comprised of curved blades. The impeller rotates within its casing and sucks the fluid through the eye of the casing (point 1 in Figure 10.1). The fluid’s kinetic energy increases due to the energy added by the impeller and enters the discharge end of the casing that has an expanding area (point 2 in Figure 10.1). The pressure within the fluid increases accordingly.

The characteristic curves of commercial pumps are provided by manufacturers. Otherwise, a pump should be tested in the laboratory, under various discharge and head conditions, to produce such curves. If a single pump is incapable of delivering the design flow rate and pressure, additional pumps, in series or parallel with the original pump, can be considered. The characteristic curves of pumps in series or parallel should be constructed since this information helps engineers select the types of pumps needed and how they should be configured.

Many pumps are in use around the world to handle liquids, gases, or liquid-solid mixtures. There are pumps in cars, swimming pools, boats, water treatment facilities, water wells, etc.  Centrifugal pumps are commonly used in water, sewage, petroleum, and petrochemical pumping. It is important to select the pump that will best serve the project’s needs.

The objective of this experiment is to determine the operational characteristics of two centrifugal pumps when they are configured as a single pump, two pumps in series, and two pumps in parallel.

Each configuration (single pump, two pumps in series, and two pumps in parallel) will be tested at pump speeds of 60, 70, and 80 rev/sec.  For each speed, the bench regulating valve will be set to fully closed, 25%, 50%, 75%, and 100% open.  Timed water collections will be performed to determine flow rates for each test, and the head, hydraulic power, and overall efficiency ratings will be obtained.

The hydraulics bench is fitted with a single centrifugal pump that is driven by a single-phase A.C. motor and controlled by a speed control unit. An auxiliary pump and the speed control unit are supplied to enhance the output of the bench so that experiments can be conducted with the pumps connected either in series or in parallel. Pressure gauges are installed at the inlet and outlet of the pumps to measure the pressure head before and after each pump. A watt-meter unit is used to measure the pumps’ input electrical power [10].

Consider the pump shown in Figure 10.3. The work done by the pump, per unit mass of fluid, will result in increases in the pressure head, velocity head, and potential head of the fluid between points 1 and 2. Therefore:

While pumping fluid, the pump has to overcome the pressure loss that is caused by friction in any valves, pipes, and fittings in the pipe system. This frictional head loss is approximately proportional to the square of the flow rate. The total system head that the pump has to overcome is the sum of the total static head and the frictional head. The total static head is the sum of the static suction lift and the static discharge head, which is equal to the difference between the water levels of the discharge and the source tank (Figure 10.4). A plot of the total head-discharge for a pipe system is called asystem curve; it is superimposed onto a pump characteristic curve in Figure 10.5. The operating point for the pump-pipe system combination occurs where the two graphs intercept [10].

Pumps are used in series in a system where substantial head changes take place without any appreciable difference in discharge. When two or more pumps are configured in series, the flow rate throughout the pumps remains the same; however, each pump contributes to the increase in the head so that the overall head is equal to the sum of the contributions of each pump [10]. For n pumps in series:

The composite characteristic curve of pumps in series can be prepared by adding the ordinates (heads) of all of the pumps for the same values of discharge. The intersection point of the composite head characteristic curve and the system curve provides the operating conditions (performance point) of the pumps (Figure 10.6).

Parallel pumps are useful for systems with considerable discharge variations and with no appreciable head change. In parallel, each pump has the same head. However, each pump contributes to the discharge so that the total discharge is equal to the sum of the contributions of each pump [10]. Thus for  pumps:

The composite head characteristic curve is obtained by summing up the discharge of all pumps for the same values of head.  A typical pipe system curve and performance point of the pumps are shown in Figure 10.7.

d) Record the pump 1 inlet pressure (P1) and outlet pressure (P2). Record the input power from the watt-meter (Wi).  (With the regulating valve fully closed, discharge will be zero.)

d) Record the pump 1 and 2 inlet pressure (P1) and outlet pressure (P2). Record the input power for pump 1 from the wattmeter (Wi). (With the regulating valve fully closed, discharge will be zero.)

Correct the pressure rise measurement (outlet pressure) across the pump by adding a 0.07 bar to allow for the difference of 0.714 m in height between the measurement point for the pump outlet pressure and the actual pump outlet connection.

In each of above graphs, show the results for single pump, two pumps in series, and two pumps in parallel – a total of three graphs. Do not connect the experimental data points, and use best fit to plot the graphs

Need a pump? No like a REAL pump, something that"s going to make your arms feel like they don"t belong to your body. Well, that"s what the stimulant free pre workout Hydraulic, designed by Seth Feroce, is for. If you"re using a stim pre, use half a scoop prior to training to complement it. But if you don"t use a stim pre, go full pump serving 2 scoops - you won"t regret it.

What makes Hydraulic a sick pump product? The formula. And we"re not talking about the crazy labels. Hydraulic packs a full dose of Citrulline, one of the most common pump ingredients on the market today, paired with patented ingredients like Glycerpump and Taurine to promote blood flow and water transport. One of the more expensive ingredients in Axe & Sledge Hydraulic is the Creatine Magnapower which is bonded to a magnesium molecule for better absorption and easier on the stomach.

Nitrosigine, another arginine derivative, has been wildly popular in the supplement market and Hydraulic packs a full dose of it! To round off Hydraulic even further, nootropics like L-Tyrosine are added to the formula to enhance focus and added beta alanine to get the full pre feel.

If you"re looking for increased blood flow and great pumps in the gym, whether low carb, no carb, or high carb, Hydraulic is here. For crazy pumps, stack with Axe & Sledge Demo Day. For some added stim, stack withIgnition Switch.
