1 INSTALLATION 1.1 UNPACKING After unpacking, the pump should be checked for any damage that may have occurred during shipment. Damage should be reported to the carrier immediately. The following items should be included within the shipping container: Qty 1 1 1.2 Item M50D MM50D Description Maxim 50D Pump Operation/Maintenance Manual UTILITIES / HOOK-UP It is recommended that the pump be positioned within 15 from level to maintain self-priming ability and pumping efficiency.
Figure 1-1 ATTENTION: The pump should be operated with clean, dry air or nitrogen. Particulate, water and oils in the air supply can damage the pump. NOTE: 1. It is recommended that a filter be placed on the discharge side of the pump. 2. Although extensive efforts are made to deliver pumps to our customers completely dry, new pumps may contain residual moisture from their final DI water test. Recommended Maximum Operating Levels: See Figure 3-2: Pressure vs.
1.3 REMOTE EXHAUST HOOK-UP Remove existing Muffler Assembly from pump base. Install Exhaust Plug in Exhaust Port. Remove Pipe Plug (1/4” NPT) from the pump base. Install the appropriately sized fitting and tubing (not provided) to remote exhaust. NOTE: To maintain optimum pump performance use 3/8” tubing minimum at a length of 10 ft. maximum.

NOTE: See Surge Suppressor Operation Manual for detailed installation instructions. 2.3 OPTIONAL LEAK SENSING 2.3.a Installation Remove plug and seal from port. Probe is self-sealing. Install probe assembly into leak sensor port. Thread probe cap into port. (NOTE: Do not over tighten; damage to threads will occur.) Push protective tubing into probe cap.
3 START-UP Pump air supply pressure must be regulated (< 80 psig). Open the fluid suction (IN) line valve, if necessary. Open the fluid discharge (OUT) line valve, if necessary. Start with air regulator at low (> 20 psi) pressure setting. Increase pressure to attain desired flow, up to the maximum rating (See Section 3.1). Table 1: Consumption / Efficiency can be used to determine approximate air consumption. Refer to Troubleshooting, Section 5, if pump fails to start.

Figure 3-2: Pressure vs. Fluid Temperature Chart Recommended Maximum Pump Operating Levels NOTE: 1. This graph is not representative of all operating conditions - customer’s specific application results may vary. 2. Be sure that fittings and tubing used are capable of these operating conditions.
4 MAINTENANCE Trebor pump maintenance can be divided into two categories: air system maintenance and fluid system maintenance. The purpose of air system maintenance is to prevent air system failures such as stalling or erratic cycling. The purpose of fluid system maintenance is to maintain suction and lift capabilities. Pump Rebuild Service Trebor International provides a factory rebuild service for customers using Trebor products. Trebor will rebuild any standard pump (exclusive of options).

4.7 DISASSEMBLY During the life of the pump it will be necessary to perform certain preventative maintenance procedures to ensure its continued high performance. This section and the next (4.8 Assembly) are provided for the user’s convenience in disassembly and re-assembly procedures. Loosen quick grip nuts on the transfer tubes from the pump base using 13/16” open-end wrench. Remove pump assembly from the pump control base.
Figure 4-2 Remove head and check diaphragms for cracks or cuts. To remove diaphragms, slit diaphragm with a sharp knife and pull the diaphragms from the grooves. (Do not pry on diaphragm seal groove, as this will damage the sealing surface.) Unscrew push plate from the shaft in a counter-clockwise direction. Pull other push plate and shaft from pump body. CAUTION: Following disassembly, parts should be thoroughly washed and be free from chemical residue for handling purposes. 4.7.
Using pH test strips evaluate whether base has any contamination in air passages, especially the muffler area. If present, neutralize using best methods prior to disassembly. Unscrew and remove muffler assembly from base using the 1”pin tool. Unscrew and remove the shuttle cap and seal. Remove shuttle spool assembly from detent adapter. Remove detent legs and detent ring from spool. Remove detent adapter from base using 3/4” pin tool.
Figure 4-3 Insert spool assembly into detent adapter and shuttle sleeve (do not lubricate spool or sleeve). Install seal onto seal groove shoulder Thread shuttle cap onto detent adapter, torque to 40in-lbs. Figure 4-4 ATTENTION: Threads should be snug. Do not over tighten. Thread muffler assembly into base using 1” pin tool, torque to 40in-lbs. 4.8.b Body Assembly Install seal and damper plug into body using 3/4” pin tool, torque to 50in-lbs. Remove pump from assembly fixture.
Install discharge check cage into bore making sure small end fits into relief in bottom of bore. Drop ball into check cage, then O-ring. Install suction sleeve into the bore; tighten using 1” pin tool. Tighten until engagement with O-ring is achieved, then unthread the sleeve a quarter turn. Do not over tighten as damage may occur. Install second ball into check cage, then O-ring. Install suction seat using the 1” pin tool.
Install union nut on pump while gently pressing down on the head to engage tabs in head and body, spin union nut down hand tight. Turn pump over and remove union nut to install diaphragms. Repeat diaphragm, head and union installation. Lock body into mounting fixture. Using strap wrench, torque union nuts slowly to 75 ft-lbs with the wrench at 90° +/- 15° to the nut’s surface as shown. Figure 4-6 4.
Increase the air pressure until the pump starts to cycle Record the start pressure, Target = <20psig Pump must prime once even cycling is achieved Increase pressure to 60 psi Check for fluid leaks & listen for air leaks Ensure that the pump does not cycle erratically Close the discharge valve and deadhead for 2 minutes Pump must not experience machine gunning, erratic cycling or leaks Open discharge valve and expel the remaining DI water Prepare the pump for drying 4.
5 TROUBLESHOOTING Pump Will Not Start, Fails to Operate Cause: Insufficient air pressure. Solution: Must be minimum 20 psig at pump air hook-up. Insufficient air volume (low supply pressure during running). Fluid discharge line blocked. Downstream valve closed, filter plugged or other obstruction. Pilot valve failure. Detent failure. See Performance Charts (3.1) for requirements. Check for both regulator and control valve capabilities. Remove obstruction.
