OPERATIONS INTENDED USE The standard Fristam FCM Colloid Mill versions are designed for use in hygienic applications. Each mill is specified according to customer specifications, including performance and materials of construction. The pump may only be used for the application it was specified for.
Maintain good piping practices (see below). CLEANING SIP PROCESS FCM Colloid Mills should only be used for SIP (Sterilization In Place) process with the prior approval of Fristam. Suitability may depend on selected elastomers and/or process temperatures. CIP PROCESS FCM Colloid Mills are suitable for the CIP (Cleaning In Place) process. The following is a general example of the CIP process: •...
PIPING CAUTION: Because the FCM Mill is highly efficient, the user needs to ensure that the mill will not be over-pressurized during operation as this can cause severe damage to the mill. (Over-pressurization can occur if a valve is closed on the discharge and the mill continues to run beyond its maximum pressure rating.) The mill warranty is void for damage caused by over-pressurization.

FCM Colloid Mill • Avoid sump areas where sediment may FIGURE 3 collect (figure 3). • Use a check or “foot” valve on the inlet side of the mill in lift applications to keep the suction piping flooded. • Avoid throttling valves in the suction piping.

FCM Colloid Mill ALIGNMENT In most cases, the mill will be shipped with a drive unit mounted on a baseplate. The drive and mill are aligned at the factory; however, this alignment should be checked after installation (Figure 7). Misalignment between the mill and drive can result in premature bearing failure or other damage. If the mill is not shipped with a drive unit, use a flexible coupling between the mill and drive unit.

FCM Colloid Mill ELECTRICAL CONNECTIONS Have an electrician connect the drive motor using sound electrical practices. Ensure that proper motor overload protection is provided. The size of the drive selected should meet the requirements of the operating conditions. A change in conditions (for example, higher viscosity product, higher differential pressure can overload the motor.
FCM Colloid Mill RECOMMENDED PREVENTIVE MAINTENANCE RECOMMENDED SEAL MAINTENANCE Visually inspect mechanical seal daily for leakage. Replace mechanical seal annually under normal duty. Replace mechanical seal as often as required under heavy duty. When replacing ANY seal part, it is important to replace ALL seal wear parts.
FCM Colloid Mill ADJUSTING THE GAP It is not necessary to disassemble the mill in order to change the width of the gap. The casing channel is marked with minimum (0.2 mm) and maximum (2.0 mm) values and percentages in between.
FCM Colloid Mill MILL DISASSEMBLY REMOVE THE COVER, STATOR, AND CASING • Before disassembly, adjust the stator to the maximum gap. • Disconnect the flush water supply from the pump. • Disconnect the top flex push-to- connect flush water tube from the casing.
FCM Colloid Mill SEAL REPLACEMENT MECHANICAL SEAL REMOVAL • Place the housing seal side up on an even surface. • Loosen the 2 seal retainer bolts • Remove the seal retainer. • Remove the flush seal from the shaft. •...
FCM Colloid Mill MILL ASSEMBLY HOUSING INSTALLATION • Slide the housing over the shaft until it meets the flange. Be careful not to damage the seal. • Install the flange bolts and tighten to the proper torque. • Install the rotating seal onto the shaft.
FCM Colloid Mill STATOR DISASSEMBLY (OPTIONAL, AS NEEDED) • Remove the gap adjustment handles without marring their outside diameters. • Remove the other 8 cover nuts and washers. • Remove the cover from the casing. • Inspect the cover gasket for damage.
All orders are subject to acceptance by Fristam Pumps USA Limited Partnership. Each Fristam Pumps item is warranted to be free from manufacturing defects for a period of one (1) year from the date of shipment, providing it has been used as recommended and in accordance with recognized piping practice, and providing it has not been worn out due to severe service, such as encountered under extremely corrosive or abrasive conditions.
