Shri Madhav Instruments

• Single/Double Acting Pump Setup: Demonstrates performance of single or double-acting reciprocating pump under various conditions.
• Transparent Pump Head (Optional): Some models feature acrylic cylinder heads for visualizing piston movement and valve operation.
• Motor-Driven Mechanism: Fitted with an electric motor (0.5 – 1 HP) to drive the pump via crankshaft mechanism.
• Water Circulation System: Includes sump tank, suction pipe, delivery pipe, and discharge tank for closed-loop operation.

Reciprocating double acting pumps are positive displacement pumps. This unit is a self- contained recirculation type unit.

• Eco-Friendly Refrigeration System: Demonstrates the vapor absorption cycle using ammonia-water or lithium bromide-water pair as refrigerant and absorbent.
• No Compressor Required: Uses heat energy (electric heater or gas burner) instead of mechanical energy for operation.
• Complete Cycle Components: Includes generator, condenser, evaporator, absorber, analyzer, and rectifier arranged in sequence for clear visualization.
• Instrumentation Panel: Equipped with thermometers, pressure gauges, flow meters, and digital displays to monitor process parameters.
• Heater-Controlled Generator: Heating input to the generator is controlled via digital temperature controller or variac.
