TKM K Series Metering Pumps Operation Manual 1. Introduction to TKM K Series Metering Pumps This instruction manual is to provide the end user with an extensive understanding of TKM Metering Pumps. The information provided in these instructions includes important guidelines for the safe and successful installation, operation, and maintenance of TKM K Series Plunger Metering Pumps.
• Environmental hazards from chemical leaks and pipeline bursts 2.4 Importance of TKM Authorized Spare Parts Modification of the TKM Pump is not permitted. Repair of the TKM Pump Liquid End is only permitted after authorization from TKM LLC. Only genuine spare parts approved by TKM may be used to service the pump.
3. Manufacturer’s Warranty TKM Metering Pumps, as well as other TKM products, are under a manufacturer’s warranty for a period of two years (24 months) from the Manufacturer’s shipping date. The warranty covers replacement, free of charge, of any defective components deemed unsuitable by the TKM technical office.
TKM Pump, replacing the TKM Pump, or refunding the original purchaser, who may be the End User or the Distributor, but not both, up to the full purchase price. TKM LLC shall not be held responsible for any removal or replacement cost, or any additional consequential damages.
• Stainless steel hardware 5. Receiving and Storing a TKM Pump All TKM Metering Pumps and TKM products are shipped from TKM LLC in excellent condition after undergoing thorough testing. TKM LLC carefully assembles each pump to the specified needs of the End User. The pump should only be used for the application intended and agreed to with TKM LLC.
5.2 Storing a TKM Pump If the TKM Pump is not used immediately, the End User should store the pump in a dry, clean, and weatherproof environment. To prevent soil moisture, it is best to place the pump off of the ground on a shelf or on wooden pallets.
TKM K Series Metering Pumps Operation Manual Only Qualified Personnel should be responsible for the storage of the TKM Pumps. Always check the dimensions and weight of the TKM Pump before handling or lifting. 6. Technical Data The main housings for KP Pumps are constructed of cast aluminum. The aluminum castings are then fully anodized and powder coated for added chemical resistance.
6.4 Noise Levels The average level of noise emitted by the K Series Metering Pumps varies depending on the material of the Liquid End, and the size of the Liquid End. The following table shows the average noise levels detected from four KP Pump prototypes at a distance of 3 feet (1 meter) from the pump: KP Pump Model –...
The following pump model is designated by the notation above (KP15S75/3 HP): A. K series Plunger Pump, B. Plunger Diameter 15 mm, C. 316L Stainless Steel Liquid End, D. 75 Strokes per Minute (SPM), E. Standard Stainless Steel Valve Balls, F. Aflas Valve O-rings, G.
TKM K Series Metering Pumps Operation Manual F. Valve Seal Material – Depending on the application, the O-rings in the valves will change: o BLANK – FKM o E – EPDM o A – Aflas o P – PTFE Seals G.
Do not fasten the pump from any other threaded holes located on the pump. 7.1 Mounting a TKM Pump The following guidelines will assure that the TKM Pump is installed in a location that is ideal for the efficient performance of the pump and convenient for routine maintenance and inspection.
• When installing the pump outdoors in a warm climate, TKM recommends covering the pump to prevent direct sun exposure and overheating. • When installing the pump in cool climate, TKM recommends installing the pump in an enclosure that is warmed and insulated to prevent the chemical from solidifying within the Liquid End and the valves.

TKM K Series Metering Pumps Operation Manual Figure 4 - Avoid rounded tubing in suction line to prevent air in suction line 7.2.1 Suction Line Filters A filter in the form of a basket strainer or y-strainer on the suction piping is always recommended to prevent insoluble substances and debris from entering the pump’s valves.
TKM K Series Metering Pumps Operation Manual Figure 6 - Using a foot valve with a strainer when suction line runs into reservoir tank 7.3 Connecting the Discharge Piping The discharge pipe should always be equal in size or larger than the pump suction connection.
TKM K Series Metering Pumps Operation Manual The pressure relief valve should always be installed before the back pressure valve. Always position the pressure relief valve as close to the pump as possible. The pressure relief valve should be set no higher than the maximum working pressure shown on the pump’s nameplate to prevent...
TKM K Series Metering Pumps Operation Manual Note: The back pressure valve should be located after the pressure relief valve and the pulsation dampener. Always position the back pressure valve as close to the pump as possible. The back pressure valve should be set no higher than the maximum working pressure shown on the pump’s nameplate (minimum...
Figure 10 - Recommended configuration for TKM Pump system 7.5 Flushing the Liquid End Always flush the valves whenever the TKM Pump has been turned off. This will prevent the chemical or other fluid from solidifying inside the valves. Flushing the valves will greatly improve their longevity and performance.
100% to 0% stroke length depending on necessary flow rate. 8.2 Stroke Length Adjustment The TKM Metering Pump is fitted with a stroke length adjustment knob, hereafter referred to as the knob or the adjustment knob. The adjustment knob allows the End User to determine the flow rate of the TKM Pump.
TKM K Series Metering Pumps Operation Manual 8.2.1 Adjusting the Stroke Position To adjust the stroke length, turn the adjustment knob in a clockwise or counterclockwise direction. The stroke length decreases when turning the knob in a clockwise rotation. The stroke length increases when turning the knob in a counterclockwise rotation.
End in only one direction. The valves are engineered to improve accuracy and prevent backflow through the pumping system. The TKM KP Plunger Pump’s valves are composed of stainless steel (SS). There are four distinct pieces that make up each check valve: the ball, the guides, the seat, and the valve housing.
8.3.2 The Plunger and Packing The TKM KP Pump is designed with a SAF 2205 duplex steel plunger fitted for the Liquid End. The plunger acts as a piston within the Liquid End and is the main source of suction and discharge in the Liquid End.
End User, or the End User can source the motor independently. The motor controls the initial speed of the worm shaft. TKM pumps are all rated at 1750 RPM and require motors that range from 1/2 horsepower – 1 horsepower.
TKM K Series Metering Pumps Operation Manual 7. Mount the motor onto the TKM Pump’s motor flange ensuring that the motor coupling on the motor and the motor coupling on the TKM Pump align directly with one another when mounting.
10. Servicing a TKM KP Pump The TKM KP Pump is manufactured for maximum durability in the field. However, after running for an extended period, the KP Pump will require routine maintenance and service including rebuilding the valves and replacing the packing.
TKM K Series Metering Pumps Operation Manual Replacing the valves and the packing once a year or when necessary will ensure that the KP Pump continues to perform as expected. 10.1 Rebuilding the Check Valves The KP Pump will require a valve rebuild 12 to 18 months after installation. This process replaces all the components within the valve housings of the pump.
Figure 13 - Correct orientation for suction valve 10.2 Replacing the Standard KP Plunger Packing Similar to the check valves, the packing requires replacement every 12 – 18 months. TKM recommends replacing the packing at the same time as the valves.

Figure 15 - KP High-Pressure Pump Liquid 10.4 Changing the Gear Oil TKM recommends changing the gear oil one time every 12 months. Changing the gear oil will ensure that the internal components of the pump stay lubricated. Keeping the internal components lubricated will greatly increase the longevity of the TKM Pump.
10.5 Troubleshooting the TKM KP Pump If a TKM Pump begins to malfunction, please follow the troubleshooting guide in order to successfully diagnose the problem. If an issue arises which cannot be diagnosed by Authorized Personnel, the TKM Pump will have to be returned to TKM LLC for repairs.
