IV. Installation
Description
This section covers the general information and cautions about installing your pump as well
as specific steps to take during installation.
Location
Locate the pump as near to the liquid source as practical and below the level of the liquid
for automatic self priming. If the pump must be above the liquid source, a foot valve must
be provided on the suction pipe.
Allow adequate space around the pump for servicing and ventilation.
Protect the pump and piping from freezing temperatures.
Provide other weather protection consistent with the motor enclosure rating. The maximum
ambient temperature for the pump is 104°F (40°C).
For installation at altitudes greater than 3,000 feet (1,000 meters), the pump selection
should be de-rated due to the difference in barometric pressure. Contact your Goulds Water
Technology distributor for assistance in selection.
Foundation
The unit must be securely affixed to a leveled concrete or metal base foundation that is
adequate to absorb vibration and to provide permanent, rigid support for the pump and
motor assembly. If the unit is to be installed on a concrete foundation, hold down bolts
should be sunk in concrete and aligned with the holes in the feet. When the concrete has
dried, tighten nuts to keep the pump firmly in position.
Your SMVT pump has been supplied with a rigid base pump body with two feet. The
mounting dimensions are shown in Figure 2.

Installation of Mechanical Seal to Pump Assembly
Your SMVT pump has been shipped with the pump assembly and mechanical seal
disassembled.
1. Remove the (2) coupling guards.
2. Lubricate the inside of the mechanical seal assembly (supplied with pump) with grease
(such as Armored AutoGroup “STP” or Dow Corning “111 Grease”) or a mixture of
equal parts non-petroleum hand soap and water. Be sure that there is an o-ring at the
back of the gland flange.
