A Few Features To Look For In Foundation Repair Hydraulic Pumps
Foundation repair is a labor-intensive, delicate process, so you’ll want a hydraulic pump that’s designed for the job. Here’s what to look for:
Product Certification
Hydraulic pumps are available that come certified by reputable resting agencies. One such agency is the Canadian Standards Association, or CSA. A CSA-approved model is one that has been tested by CSA for performance and safety, so it comes recommended by the experts.
Two-Stage Pump Operation
Two-stage pumps are preferred over single-stage pumps in many applications, including foundation repair. That’s because two-stage pumps offer several advantages. For example, two-stage pumps can operate in parallel for better volume or switch into a higher-pressure mode when needed. Two-stage pumps also last longer and come with added cost efficiency, as a result.
Universal Motor Design
Universal motors are economical and smaller than other types of motors, so they’re a good choice for applications where the motor will be carried around a bit. Universal motors can run on AC power.
Breather and Filler Caps with Filters
You’ll want a hydraulic pump that keeps contaminants away from wearing surfaces. You’ll also want a hydraulic pump that can protect itself from air seeping into the system. Filtered breather and filler caps do both. As hydraulic fluid is pulled in, filters remove particles and allow air to escape if fluid levels change during operation.
A Liquid-Filled Pressure Gauge
A liquid-filled pressure gauge allows for easy pressure readings even when conditions are not ideal. Foundation repair is loud, heavy work that involves a lot of vibrations. A liquid-filled gauge maintains stability even when subjected to vibration, so you can still read it easily. Liquid-filled gauges tend to last longer, too, as the additional lubrication reduces wear.
A Nifty Carrying Handle
You’ll be carrying around your foundation repair hydraulic pumps a lot, and a carrying handle makes this process much easier.
How Are Hydraulic Pumps Used In Foundation Repair?
Hydraulic pumps are responsible for inputting the energy needed to lift and stabilize a damaged foundation. How exactly that energy is applied depends on the foundation repair method. Here’s a closer look:
Concrete or Steel Piering
Piering is a primary means of foundation repair, using metal or concrete supports to bear the foundation’s weight and push it back in place. To get those piers in place, holes are dug around the foundation and inserted under it.
Once in place, jacks and hydraulic cylinders are temporarily installed at the top of these piers. A hydraulic pump delivers pressurized fluid to the cylinders, which convert this fluid energy into linear lifting force. The cylinders lift the piers into position and when the foundation is leveled out, the piers are capped at the top and ready to bear weight for many decades.
Slabjacking (or mudjacking)
Slabjacking is an economical and faster alternative to concrete or steel piering. During slabjacking, a series of small holes (2” or less in diameter) are drilled into settled pieces of the foundation slab. Once the holes are drilled, a grout-like mixture is pumped through the holes and under the foundation.
Hydraulic pumps are responsible for pumping this material beneath the foundation. When all pieces of the slab have been lifted to the desired height, the holes and any gaps in the foundation are filled with a concrete mixture.
How Does A Hydraulic Pump Work?
Gear Pumps
During operation, gear pumps spin a pair of gears that create a vacuum at the inlet, “pulling” in fluid as a result. This fluid circulates around the gears, trapped between the housing and gear teeth. The fluid exits out opposite the inlet. The gears’ orientation is such that a perfect seal is maintained during operation.
Axial Piston Pumps
Axial piston pumps work by rotating a series of pistons against an offset surface, typically referred to as a swashplate. On the intake side of the rotating barrel, the swashplate is angled away from the piston barrel. This pulls the pistons away from the intake port and creates a vacuum that pulls in fluid. On the discharge side, the swashplate is angled toward the piston barrel, pushing the pistons toward the discharge port and pushing fluid out as a result.
Four Signs That Your Hydraulic Pump May Need A Repair
Hydraulic pumps operate for extended periods in rugged environments. As such, they need regular service and the occasional repair to maintain performance. Is it time for your hydraulic pump to see our team? Here’s four signs that it might be time for a hydraulic pump repair:
- It’s making a lot of noise – You’ll get used to the way your hydraulic pump sounds. If it starts sounding different, that could be a concern, especially if there’s a rattling or banging sound present.
- It’s slowing down – As pumps age and as their wearing surfaces wear down, drops in performance may occur. Eventually, some pumps slow down to the point of being rendered useless, but regular service can extend the pump’s life.
- It’s leaking (externally or internally) – Leaks will reduce pump performance and can result in catastrophic failure if not addressed. Sometimes, the leak will spring from another part of the system and not from the pump itself, but this should still be checked to protect performance.
- It’s heating up too much – If airborne contaminants jam up the pump’s filters, this will make it difficult to control heat levels inside the pump. Eventually, this excess heat will warm up the hydraulic fluid, causing system-wide degradation if not handled.
