3 Company overview • Sippican is a company manufacturing hydraulic control devices: valves‚ pumps and flow controllers • Recent trends (March 2006) Valves: margin remained at standard 35% Pumps: Sippican’s main business‚ gross margin fell to 5% (below expect. 35%) Flow controllers: price increase by 10% with no effect on demand • Issue Sippican had to react to competitors pumps price reductions to maintain volumes Decline in profitability: pre tax margin to less than 2% 4

circulation through the whole body. 10. Explain the characteristics of peristaltic (roller) pumps in life support devices? 11. Explain the characteristics of rotary pumps in life support devices? 12. Explain the advantages of rotary pump over pulsatile pump. 13. Explain the possibilities of using an implantable VAD without percutaneous lead. 14. With a help of a diagram‚ demonstrate how a centrifugal pump could be used as a VAD. 15. Discuss the considerations/requirements in designing VAD. 1

the primary pump which that makes the blood to flow as well as changes in velocity. The blood velocity then oscilates from zero velocity to to very high velocities as the entrance and exit valves intermittently close and open with each beat. The second pumping effect results from the respiratory and skeletal systems. These acts on the venous flow [10]. The resulting pulsation as the blood is released from the left ventricle shows that the flow

70‚ pump unit cost=$48.79‚ flow controller unit cost=$100.91. ( see table 1) 2. Standard unit costs and revised unit costs both show that the highest product cost is pump product line. However‚ our transaction-based analysis shows it should be the flow controllers. We can tell that the unit costs have been badly distorted as a result of using single allocation basis (production-run labor cost).

new system are different from exhibit 3 and 4. Unit price for valves has a slight change compare to the standard unit price‚ but for pumps and flow controllers‚ there is a dramatic change. Destin Brass are well under their 35% gross margin goal for pumps‚ and wondering how other companies can sell their pumps for such a low price. They thought the unit costs for pumps is $63.12‚ when in fact‚ the more accurate system shows that it’s

gain market share by cutting price. Therefore the competitive situation for valves was not so fierce that Wilkerson could maintain its gross margin. (2) Pumps Pump product line’s characteristic is high-volume and the manufacturing process for pumps was practically identical to that for valves. Due to the severe competitive situation for pumps‚ its market price has reduced continuously‚ so that Wilkerson had to match the low price to maintain its market share and sales volume.

From dry tank to main tank‚ there is another pipe connection. This is over flow pipe. This pipe connection is used to return the oil from dry tank to main tank in the event of over flowing. From dry tank the oil is injected in the diesel engine by means of fuel injection pump. Air Intake System This system
