LEVEL BASEPLATE 1. Place 2 sets of wedges or shims on the foundation, one set on each side of every foundation bolt. The wedges should extend .75 in. (20 mm) to 1.5 in. (40 mm) above the foundation, to allow for adequate grouting. This will provide even support for the baseplate once it is grouted. 2. Remove water and/or debris from anchor bolt holes/sleeves prior to grouting. If the sleeve type bolts are being used, fill the sleeves with rags to prevent grout from entering. 3.
ALIGNMENT CRITERIA MEASUREMENT Good alignment is achieved when dial indicator readings as specified in the alignment procedure are .002 in. (.05 mm) Total Indicated Reading (T.I.R.) or less when the pump and driver are at operating temperature (Final Alignment). 1. To ensure accuracy of indicator readings, always rotate both coupling halves together so indicators contact the same point on coupling half Y. This will eliminate any measurement problems due to runout on coupling half Y.
Positive Reading - Coupling half X is higher than coupling half Y. Correct by adding shims of thickness equal to half of the indicator reading from each driver foot (Fig. 8A). Horizontal Correction (Side to Side) 1. Zero indicator A on left side of coupling half Y, 90° from top dead center (9 o’clock). 2. Rotate indicators through top dead center to the right side, 180° from the start (3 o’clock). Observe needle and record reading. 3.
4. Repeat steps 1 through 3 until indicator P reads .002 in. (.05 mm) or less. 5. Re-check both horizontal and vertical readings to ensure adjustment of one did not disturb the other. Correct as necessary. 3. Horizontal Correction (Side to Side) 1. Zero indicators A and P on the left side of coupling half Y, 90° from top dead center (9 o’clock). 2. Rotate indicators through top dead center to the right side, 180° from the start (3 o’clock). Observe the needle, measure and record the reading. 3.
4. Allow grout to set. 6. Allow grout to set at least 48 hours. 5. Fill remainder of baseplate with grout. Remove air as before (Fig. 9B). 7. Tighten foundation bolts. Alignment Check Re-check alignment before continuing, using methods previously described. Fig. 9B PIPING Guidelines for piping are given in the “Hydraulic Institute Standards” (Edition 14, Centrifugal pump section) and should be reviewed prior to pump installation. 7. 1.
Suction Lift Conditions 1. Suction pipe must continuously slope upward towards pump suction to eliminate air pockets. 2. All joints must be air tight. 3. A means of priming the pump must be provided, such as a foot valve. Suction Head/Flooded Suction Conditions 1. An isolation valve should be installed in suction line to permit closing of the line for pump inspection and maintenance. 2. Piping should be level or slope gradually downward from source of supply. 3.

Put suitable thread sealer on ¼" NPT threads on pressure switch and install switch in bell housing. 3. Mount a junction box near switch and run conduit to control room. Use flexible conduit from junction box to switch. 4. Wire switch to customer supplied monitoring system for either normally open (N.O.) or normally closed (N.C.) as shown (Fig. 1).
CONDITION MONITORING DEVICES NEMA 7 Pressure Switch (Option) Leak Detector DESCRIPTION This detector senses a leak in the containment shell by detecting pressure in the bearing frame bell housing. A pressure switch preset to trip at 10 PSIG on increasing pressure is supplied. The switch must be wired to the customer's monitoring system to sound an alarm and/or stop the pump. This liquid leak detector is identical in operation and function to the NEMA 4 pressure switch leak detector.
INSTRUCTION 1. Remove 1/4" NPT pressure switch plug (408C) from bearing frame bell housing (Fig. 2). 2. Put suitable thread sealer on 1/4" NPT threads on pressure switch and install switch in bell housing. 3. Mount a junction box near switch and run conduit to control room. Use flexible conduit from junction box to switch. 4. Wire switch to customer supplied monitoring system for either normally open (N.O.) or normally closed (N.C.) as shown (Fig. 2).
CONDITION MONITORING DEVICES Vibration Monitor (Option) DESCRIPTION The vibration monitor senses the vibration signal from an accelerometer mounted on the pump bearing frame. The monitor has two fully adjustable set points and relays. Typically, one set point is used for an alarm and the second set point is used to stop the pump. COMPONENTS SUPPLIED (1) Vibration monitor with instructions (1) Vibration transmitter (Accelerometer) Specifications Vibration Monitor Make - Balmac Inc.
MOUNTING LOCATION It is recommended to mount monitor in a control room to avoid excessive shock, vibration, dirt, moisture and oil. The transmitter must be mounted on pump bearing frame, in hole provided. Run connecting wiring through conduit. INSTRUCTION 1. After pump installation is complete, thread ½" NPT end of transmitter into hole provided in pump bearing frame (Fig. 3). Tighten until snug. NOTE: Hole is predrilled on M Group.

SET UP INSTRUCTIONS The following are setup instructions which, along with the GTP System instruction manual, will guide you through the proper setup and operation of the total protection package. Mounting Location The Goulds Total Protection System can be located most non-hazardous plant locations where a NEMA 4X enclosure is appropriate. If a NEMA 7 enclosure is required, the GTP Controller should be mounted in a separate NEMA 7 enclosure, such as a junction box, that is supplied by the customer.
High Temperature Protection The temperature circuit monitors the containment shell skin temperature and shuts down the pump once a predetermined temperature level is reached.
System Pressure This circuit, if utilized, shuts down the pump if it is operating dry or at too low a suction pressure. A user supplied pressure switch monitoring pressure in either the discharge or the suction pipe is required. This switch is not available through Goulds due to the diversity in pressure, materials of construction and connection sizes.
