Penetrating Nozzles

Penetrating Nozzles


Nozzles used for opening blockages or remove obstructions are all designed with some type of front jet(s). It can be a simple blockage caused by buildup of F.O.G (Food, Oil, Grease) sludge, hair, or larger stones or foreign objects i.e., flushable wipes preventing the flow in the pipe. When the flow slows down even more material get built up and creates a dam effect and can result in an emergency. Bellies or dips in the pipe can also cause this to occur with allows debris to build up in the bottom of the pipe and creates that dam effect.

In today’s market you find many different nozzles that are designed to open clogs or remove obstructions. From simpler Tier 1 nozzles with drilled jet holes both for thrusting rear jets and supplied with one or more forward jets to more advance Tier 2 and Tier 3 nozzles.

 These simpler nozzles have the poorest efficiency but are usually an excellent choice in smaller diameter pipes where more advanced nozzles cannot be used due to their size.

With a Tier 2 nozzle, the efficiency increases as these have replaceable jet inserts instead of drilled jet holes directly into the nozzle body (Tier 1). Tier 2 is designed with replaceable jet inserts or orifices offer a better adaptation of the nozzle to the pump capacity of the jetting truck or unit. These replaceable inserts can be made of Stainless Steel or a combination of Stainless Steel and Ceramic to suit your needs. Some of our nozzles have the possibility of four front jets, such as the MULTI-GLOBAL®, Pointed Nozzle, Fir®Pointed, GLOBAL ™ SP, and chisel nozzles.

The MASTER DRILL ™, also a Tier 2 nozzle, is supplied with one front jet that "rotates", which means that the front nozzle opens a larger area in front of the nozzle and allow the nozzle to thrust up the pipe with it rear thrusting jets which also aids in opening the blockage. This nozzle can be adapted to meet the pump capacity and increase the efficiency of the cleaning/opening of the blockage.

Tier 3 nozzles for blockages are highly efficient because the water directing design inside the nozzle, which immensely reduces pressure losses inside the nozzle as the water flows through. This gives more power at the nozzle at a lower cost since the truck can operate at a lower rpm and still reach a good working pressure at the nozzle. In our catalog our series of GOBLIN® cleaning nozzles offer different versions with one or several front jets. The series, starts with ½” hose thread up to 1-1/4” hose thread, they are suitable in pipe sizes from 4” up to 32”. GOBLIN®L has the option of four front jets.

In addition to the above, which we usually call fixed nozzles or standard nozzles, also rotating nozzles can be used. When cleaning standing pipes many of our customers use BL SPINNER® with 45-degree water jets rotating forward. The nozzle is then normally lowered down from the top of the pipe. For all types of clogs and obstructions, there are several different slow-rotating nozzles to be found in our range.

We are willing to assist to solve your clogged pipe problems, get those pipes flowing again.
