Page 6: Warnings
Personal injuries Never start the APV Cavitator before the guard above the Cavitator shaft has been securely mounted. The Cavitator contains rotating parts. Never put hands or fingers into a Cavitator while it is in operation. -
Page 7: Introduction To The Cavitator Program
With single or double mechanical shaft seal for SiC/C or SiC/SiC respectively With O-rings in EPDM or FPM (FKM) (Kalrez or others). The APV Cavitator can be delivered with all standard welded ferrules (S-Line, bevel seat, ISO, etc.) or with special aseptic connections prepared for sterile flushing. -
Page 8: Installation Of The Cavitator
Cavitator Installation of the Cavitator Positioning The Cavitator must be positioned so that the suction pipe is as short as possible and there is a falling gradient towards the suction nozzle. Keep the number of valves, bends and tee-fittings on the suction side at an absolute minimum. -
Page 9: Before Start-Up
Cavitator Before start-up Before starting the Cavitator, dismantle and clean the suction pipe and remove any foreign material in the Cavitator. Checking the Cavitator body for foreign material Remove the Cavitator housing as described below. The assembly drawing is to be used for reference. 1. -

Cavitator Assembly 1. Before remounting the Cavitator shaft, remove any dirt and grease from the motor shaft and the stub shaft’s internal clamping surface. 2. Mount the Cavitator stub shaft loosely on the motor shaft. Position the balance holes at the stub shaft above the keyway on the motor shaft. -

Cavitator Technical data Max. permissible discharge pressure of the Cavitator Do not exceed these values for the Cavitator’s discharge pressure (valid for water at 20°C (68°F). The values are also valid for the corresponding models of the Cavitator. Max. 10 bar (150 psig): Cavitator size: 8”, 12”, 14”, and 16” Tightening torque for impeller, inducer and shaft Tightening torque required for the screws in the stub shaft and for housing screws:... -
Page 15: Scale-Free Heating Duty
Cavitator Scale-free heating duty The heating is created by the internal disk friction between the rotor and the liquid. Because no hydraulic work is generated, almost all added energy is converted into heat. This will heat the product. The heating is thus generated by electrical energy added to the motor which drives the rotor. -
Page 16: Cavitation Duty
Cavitator Cavitation duty The Cavitator produces cavitation in each of the radial holes in the rotor when it rotates. This means that the greater the numbers of holes, the more cavitation is produced. In each hole hydro dynamic forces are created which cause interchange of pressure and kinetic energy. -
Page 17: Start And Stop Of The Cavitator
Cavitator 9.3.2 Start and stop of the Cavitator The start and stop of the Cavitator is very closely related to the start and stop of the feed pump. When the Cavitator is running, it generates energy and heat to the product. -

Cavitator Cleaning and sanitizing 9.5.1 Installation with CIP – systems, Cleaning in Place Cavitators are constructed so that they can easily be cleaned with CIP- methods for cleaning of processing plants. To achieve the necessary fluid velocities within the pump when cleaning, we recommend a differential pressure of 2-3 bars (29 –... -
Page 19: Manual Cleaning
Cavitator 9.5.2 Manual cleaning If desired, the APV Cavitator can also be cleaned manually; this can be done in conjunction with Disassembly for routine checks. Before starting up after idle periods of long duration, the machine should be cleaned manually and inspected. Please see section 7 on page 10 regarding inspection and maintenance. -
