Ready for connection Complete, vacuum-proof and reinforced spiral hose, ready for connection, for direct connection to the pump. With suction filter to protect the pump from damage due to dirt and with a non-return valve for a shorter suction time. The hose has a length of 7 m, a diameter of 25 mm (1") and is suitable for pumps with an external thread of 33.3 mm (G 1). Ready for connection Connect the hose directly to the suction side of the pump and suspend it in the fluid. Sealed connection The connection piece creates a completely sealed connection between the spiral hose, non-return valve and suction filter. Suction filter The integrated suction filter protects against dirt and thus damage to the pump. Durable The spiral hose is made of high-quality material and vacuum-proof reinforced (does not get clogged when sucking or in the absence of fluid), which gives the hose a long service life. Non-return valve The suction time after switching off is much shorter due to the non-return valve, so that efficient pumping is possible.
