  • Overview
    Introducing the PQR 4000 used in conjunction with the highly versatile and popular Saint Lizaigne 904 Service Saddle.

    The hugely versatile PQR4000 is an under-pressure main branch drilling machine is capable of drilling branch sizes in the range of ½”-2”. Used in conjunction with the 904, it can be operated by one person and is fast and simple to operate, with minimal service costs and is all you need to make a water service connection for Pipe diameters of 45mm to 335mm OD.

    The drilling machine allows for an assortment of connections that can be made through standard adaptors, a 904 saddle, plug or screwdown ferrule or Erhard. This allows the machine to be adaptable to a multiplicity of drilling requirements.

    The 904 Uni Saddle only requires a drilling machine to fit the BSP outlet of the clamp to enable you to drill into the pipe. The PQR4000 uses hole saw cutters and pilot drills to ensure minimal swarf enters the main and the coupon is retained for further examination (if required).
