Performance data

Flow of free air

The free air delivered by the pump at various stroke rates is as follows:-

Strokes/min	Free air delivered (litres/min)
30	6.3 litres/min
40	7.7 litres/min
50	9.4 litres/min

Performance under load

The flow and average pressure against an Amal jet no.45 at various stroke rates at 25degC are as follows:-

Strokes/min	Free air delivered	Average Pressure	Peak Pressure
	(litres/min)	upstream of Jet (kPa)	upstream of Jet (kPa)
20	3.7	36	69
30	5.2	68	115
40	6.2	98	144
50	7.1	127	175
50*	6.0	102	139

* at 35degC and 65% relative humidity.

The stroke rate required to maintain a flow of 4 litres against resistance of Amal jet No. 45 is 23 strokes/min at 25degC.  The work required per stroke is 80N at a stroke rate of 30/min.  Maximum recommended stroke rate, 50 strokes/min.

Effect of ambient temperature

The volume of free air delivered by the pump and the average and peak pressures will decrease with increasing temperature.  Typical results at 25degC & 35degC are given in the table above.
