scotch yoke hydraulic pump price

In real life scenarios with critical service valves, there are situations such as the loss of air or loss of power where a valve must be forced into a position other than its current position. In those critical times, the right accessories on an actuator will allow an operator to move a valve from closed to open or open to closed, regardless of the position it was designed to “fail” to. Max Air’s HD line of scotch yoke actuators offers this capability. Shown here is our hydraulic manual override system. A self-contained hydraulic reservoir and hand pump are utilized to power an auxiliary hydraulic cylinder and drive the actuator to the required position. The Double Acting actuator will stroke the valve, manually, either clockwise or counter clockwise as required. The Spring Return unit compresses the spring and drives the actuator to the opposite of it’s fail position. i.e. Opens a valve with a fail closed actuator or closes a valve with a fail open configuration.

Ideally, when pumping from any significant depth, you should not operate the Motorized System (Scotch Yoke Option) configured to pump into a pressurized system. The most difficult part of delivering water to a pressurized system is moving it out of the well. Once at ground level, the water can be delivered by a booster pump available at a fraction of the cost of the Motorized System (SYD Option). The only other additional cost is the tank for ambient storage, i.e., not under pressure.

The water lifted out of the well is pumped into the ambient storage tank by the Motorized System. Booster pumps designed specifically to pump into a pressure tank are available from a number of vendors, many for under $150 (US). The vendors who supply these include Dankoff, Surflo and Jabsco.

Configuring like this also raises the overall reliability of the system. Most notably, booster pumps include an integrated pressure sensor. It signals the booster pump to turns the pump on and off, according to a target pressure, when water is demanded from the pressure tank.

By contrast, any Simple Pump provides water in pulsed delivery, and therefore varying pressure, making the task of regulating flow to the pressure tank more difficult.

The task of supplying power above the 11.5V and 23.5V (for 12VDC and 24VDC systems) thresholds is more complex than many anticipate, particularly with solar-powered systems. Because most configurations using the Simple Pump Motorized System are powered using solar panels, only solar is discussed in this section.
