DDC pump screws
Quantity:
Gewicht: 0.1 kg
The DDC pump screws are used to attach the Xylem LOWARA DDC 4.2 PWM to a reservoir or a distroplate.
Four M4x25mm cylinder head screws are included. The 4mm head height ensures a flush fit with the pump. The screw can be screwed up to 8mm deep into the reservoir or distro plate, allowing the pump to be sufficiently tightened.
We recommend a torque of max. 5Nm to avoid stress cracks.
