seim hydraulic pump free sample

The SEIM PA Series Submersible 3-Screw Pump is SEIM"s best seller worldwide. These economical screw pumps are designed for submerged applications in the lube oil or hydraulic oil tank.

This is ideal for use in difficult locations where a normal pump will not fit. It’s simple yet robust construction ensure years of operability with minimal complications.

SEIM screws pumps are volumetric self-priming pumps suited to handle oils and fluids with a minimum lubricating property. The pumps design makes them intrinsically reliable and efficient in their applications.

For over 30 years SEIM has been supporting the pumping industry with their innovation and expertise in the pumping and handling of oils and viscous chemicals.

To make sure you find a swim spa that will give you the perfect swim, you’ll want to carefully examine the pumps and hydraulics, jets, current control, and shell design.

The first thing to look for is hydraulic pumps that will prevent turbulence and create an exceptionally flat swim. Swim spas with both throw and catch systems work like conveyor belts to diminish turbulence and these kinds of systems are the best for creating a smooth swim. If you aren’t sure how to judge whether a swim spa has this type of system, just ask your dealer. A knowledgeable dealer can guide you toward these types of swim spas.

Another feature to avoid is pumps that create an insufficient volume of water. Always choose a swim spa that allows you to achieve a deep, wide stroke. If you can’t do this, you’ll want to look for a swim spa with more water volume.

There are essentially two different types of swim jet. There is electronic one meaning that there is a pump, impellor, special jets and suction which are generally housed in a dedicated unit on the side of the pool. This is used to create the counter current to swim against.

The second type of swim jet is hydraulic. Rather than having any electrical parts poolside, which is arguably safer, hydraulic swim jets create a counter current by sending hydraulic pressure down lines.

We’ve seen that there are two types. The first working rather like a hot tub jet, sucks water from the pool, through the pump’s impellor and back through the specially designed jets at the front of the pool to create the current.

The next being a hydraulic system. There are essentially two parts to a hydraulic swim jet. There is the motor which sits in the pump/control room, and there is the propellor which is separate unit, connected by hydraulic lines that sits in the wall of the pool.

When the motor turns, it puts pressure on the hydraulic fluid which in turn causes the impellor to draw in water from the pool into the pool unit. This water is then returned to the pool under pressure from the return jets creating a counter current to swim against.

The power of the water streaming from your jets can be the difference between an okay workout and a great swim experience. Water flow is measured in Gallons Per Minute (GPM). Just as a guide, anything below 600 GPM isn’t going to give you much resistance. Noise— Nothing ruins a swim like an overly loud noise ringing in your ears. Swim jet systems have varying levels of noise and you want to be purchasing one that has the lowest DB of noise. Do your research, talk to the manufacturers. What I would say on this point is that the hydraulic machines tend to be quieter than the electrical ones. Bubbles — This is what I meant by saying that hot tub jets are not counter current swim machines. If your machine is going to add bubbles to your water, this means that it is adding air and you are swimming against air, not water. Do not purchase a system that adds bubbles to its stream because that means your jet is pushing through air, not your pool water. This will increase energy consumption, create a more inefficient workout for sure, and make it difficult to see. You want to be checking with the manufacturer that they are talking about a bubble-free machine.
