Suitable for pumps:

• P-140,
• P-145,
• P-100D,

Made of high-quality technical material, maintaining standards and precision.
The pressure in the discharge manifold should be 1/3 of the pressure at which the pump normally works.
When controlling the pressure, it is worth checking the condition of the diaphragm - to do this, you need to pump up air, and then gradually release it with the help of a valve. If only air escapes from the valve, it means that the diaphragm is undamaged, if the valve is leaking a mixture of air and water, the diaphragm must be replaced. It is especially important to check the membranes before winter, because the water freezing in the canopy damages it.
