Quick-Select Chart for
AES Vaporizers / AES Pumps

 


Pump Selection Charts:

LPG Transfer Pumps, as the name implies, are used to transfer LPG from the storage tanks to the vaporizer. In systems with venturi LPG/air mixing systems, they are also responsible for maintaining the pressure needed for optimum and efficient function of the venturi tubes.

All pumps are mounted on steel skids, and are primed and painted. They are equipped with constant pressure regulator, strainer, isolation valves, by-pass loops ("Summer-Bypass"), liquid filled pressure gauges, and any other components required for safe operation.

Smaller pumps up to 17 GPM are for single phase AC 115/230V 50/60Hz service. Larger pumps are for 3-phase AC 230/460V 60Hz or 400/415V 50Hz and require magnetic motor starters with overload protection. Pumps up to 45 GPM are direct-drive pumps (electric motor directly coupled to pump). Larger pumps are belt driven.

All pumps are of "positive displacement" design and use rotary vane pumps with a built-in over-pressure relief valve, designed for continuous use with high reliability.

A back pressure regulator provides stable delivery pressure by returning excess pump capacity to the storage tank.

All systems are supplied with an explosion proof motor to meet Class I, Div. 1, Group D (Flame-Proof) requirements.

Magnetic motor starters can be supplied either as a separate component, installed on the pump skid, or integrated with the system controls. If integrated with the system controls, a Start/Stop station at the pump skid is provided for local pump control.

When sizing a pump system, the nominal pump capacity should be approximately twice the nominal capacity of the LP or LP/Air system.

All AES pump systems are available with Blackmer pumps or with Corken pumps, and can be configured for various voltages and for 50 Hz or 60 Hz.

The purpose of Duplex Pump Systems is to provide maximum redundancy. They are therefore manufactured as individual pumps that only share a common skid. All bypass and isolation valves exist in duplicate and allow to use pumps in any combination: Pump 1, Pump 2, or Pump 1 and Pump 2 together. Each pump can be completely isolated so that maintenance and repair work on this pump does not affect the other pump, or the system availability.

Motor Starter Packages for 3-Phase Pumps (fits both Blackmer and Corken Pumps)

AES Starter Packages will be configured to match the selected pump size and motor, and are available for indoor installation, outdoor installation, and explosion-proof Class I, Div 1, Group D (Flame-Proof) installations. All types can also be integrated into the vaporizer/blender control system for remote monitoring and control of the pump operation. The pump operation can also be automated in response to the pressure in the storage tanks (pump will start automatically if tank pressure falls below an adjustable setpoint, and stays on until the tank pressure has recovered above a second adjustable setpoint).

Starters and thermal overload protection are required for all pumps with 3-phase motors. Pumps with single-phase motors have an ON/OFF switch directly at the electric connection box at the motor. Use option "Y" in the motor voltage specification to equip a single-phase pump with a contactor instead of the standard switch.
 
The part number of a starter package identifies the configuration of the package.
