Document title: BPM800 vs BAM800 Revision No: 1

Description: Key Variations Between The Banlaw BPM800 Series & BAM800 Series Nozzles

Issue Date: 02/06

This document outlines key variations between the outgoing BAM800 series refuelling nozzle and the recently released BPM800 series nozzles. These key changes should be observed to prevent cross-matching of parts and therefore avoid the associated risks – also detailed below. 1.0 Retainers The BPM800-025 Retainer incorporates 2 key differences to the earlier BAM800-025 Retainer.

Should either Retainer be installed into the wrong nozzle, the following consequences may occur:

• Incorrect shut-off pressure: the location of the pressure sensing port on each Retainer is unique to the type of nozzle. Installation of the wrong Retainer will alter the shut-off pressure of the nozzle leading to either premature nozzle shut-off or increased pressurisation of the fuel tank.

• Fuel Leakage: the trailing edge profile of the Retainer suits the specific type of sleeve seal – either O’ring (BAM series) or one-piece seal (BPM series). Installation of the wrong Retainer may lead to minor leakage of fuel from between the Retainer and Sleeve when the nozzle is in the OFF position or disconnected from the Receiver.

2.0 Sleeves The BPM800-024 Sleeve incorporates 2 key differences to the earlier BAM800-024 Sleeve:

1. the use of twin (series) AUS22-020 U-seals as opposed to the earlier pair of AUS21A-020 U-seals.

2. a one-piece moulded and vulcanised face seal replacing the inner and outer o’rings used in the BAM series. The profile of this one-piece seal has been custom designed to suit the dual role of providing a seal between the Sleeve and Retainer and an effective seal between opposing faces of the Sleeve and the Receiver during refuelling. Bench testing and field trials have demonstrated the superior performance, durability and longevity of the one-piece seal.

Should either Sleeve be installed into the wrong nozzle, leakage may occur between the Retainer and Sleeve when the nozzle is in the OFF position or disconnected from the Receiver – see also “Fuel Leakage” in section 1.0.

3.0 Piston Springs Different springs are used within the BPM and BAM nozzles to achieve equivalent shut-off pressures. Whilst springs may at first glance to appear the same, proper stock control and part number identification must be maintained to minimise the risk of cross-matching. Table 3.0 identifies the springs and their respective dimensions. Spring Settings Part No. Free Length OD Wire Dia. Total Coils

AUS21A029 86.9 ± 0.5mm 34.0 3.15 8.5 Light, Light-Med, Medium BP800-029 85.0 ± 0.5mm 34.0 3.15 8.5

Table 3.0 – Piston Spring Dimensions

The use of an incorrect spring will create the following risks:

1. incorrect shut-off pressure of the nozzle causing either premature nozzle shut-off or increased pressurisation of the fuel tank.

2. overstressing the spring causing yielding and subsequent loss of properties. Any spring outside the specs detailed in Table 3.0 should be discarded.
