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 M50R-X12 MM50R-X12 Description Maxim 50R-X12 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.
2 OPTIONS 2.1 FLUID PORT CONNECTION OPTIONS All M50R pumps with –X12 option have integrated ¾” Super 300 Type Pillar® fluid ports. 2.2 FLUID FITTINGS / SURGE SUPPRESSOR HOOK-UP Surge Suppressor SS85 SS95 Assembled Height: IN (CM) 17.12 (43.49) 13.97 (35.48 Figure 2-1 NOTE: See Surge Suppressor Operation Manual for detailed installation instructions.
2.3 OPTIONAL LEAK SENSING 2.3.a Installation Remove plug 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. Connect fiber optic cable to sensor (NOTE: Minimize bends in fiber optic cable to 2” radius minimum to help ensure optimum signal strength.) Fiber optic cable can be cut to desired length using the cable cutter provided. 2.
3 START-UP Pump air supply pressure must be regulated. (See Figure 3-2: Pressure vs. Fluid Temperature Chart) 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.
Figure 3-1: Pressure & Capacity Chart NOTE: Test information is based on specific conditions and limited sampling. Use for general reference only. 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.
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.
4.7.d Cleaning 4.8 Gently spray clean or dunk rinse all components with DI water to remove any trace materials remaining after disassembly. ASSEMBLY Prior to beginning assembly, inspect all parts to ensure they are clean and dry. Wear clean protective gloves. Precautions should be exercised to prevent contaminating any of the air chamber surfaced with chemicals during handling. 4.8.a Control Base Assembly Thread detent adapter into shuttle bore using 3/4” pin tool.
Thread shuttle cap onto detent adapter hand tight. Figure 4-4 ATTENTION: Threads should be snug. Do not over tighten. Thread muffler assembly into base using 3/4” pin tool. 4.8.b Body Assembly Install seal and damper plug into body using 3/4” pin tool. Remove pump from assembly fixture. Turn pump upside down to access check bores. 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.
Figure 4-5 Remove shaft insert tool and thread second push plate onto main shaft. Tighten snug; do not over tighten as damage may occur. 4.8.c Final Assembly Reattach pump to assembly fixture. Attach union nut to one side of pump body (hand tight). Do not install diaphragm on this step. This will protect body during initial pump assembly. Remove pump from the assembly fixture.
Reinstall transfer tubes in head ports using latex gloves for added grip. Ensure transfer tubes are tight. Thread pilot seat into head using 3/4” pilot centering pin tool. Install pilot poppet into pilot seat. Position pilot cap seal into bore and thread in pilot cap using 3/4” pin tool. Position control base on mounting base, slide base forward, use locking lever to secure. Loosely attach quick grip nuts to transfer tube ports on control base.
5 TROUBLESHOOTING Pump Will Not Start, Fails to Operate Cause: Insufficient air pressure. 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. Solution: Must be minimum 20 psig at pump air hook-up. See Performance Charts (3.1) for requirements. Check for both regulator and control valve capabilities. Remove obstruction. Inspect and replace pilot valve body and poppet.
